|
|
IMPORTANT
|
|
Custom configuration is now specified in localoptions.h rather than options.h
|
|
Available options and defaults can be seen in default_options.h
|
|
|
|
To migrate your configuration, compare your customised options.h against the
|
|
upstream options.h from your relevant version. Any customised options should
|
|
be put in localoptions.h in the build directory.
|
|
|
|
- "configure --enable-static" should now be used instead of "make STATIC=1"
|
|
This will avoid 'hardened build' flags that conflict with static binaries
|
|
|
|
- Set 'hardened build' flags by default if supported by the compiler.
|
|
These can be disabled with configure --disable-harden if needed.

Patch from CamVan Nguyen
|
|
|
|
- group1-sha1 key exchange is disabled in the server by default since
|
|
the fixed 1024-bit group may be susceptible to attacks
|
|
|
|
- twofish ciphers are now disabled in the default configuration
|
|
|
|
- Default generated ECDSA key size is now 256 (rather than 521)
|
|
for better interoperability
|

|
2017.75 - 18 May 2017
|
|
|
|
- Security: Fix double-free in server TCP listener cleanup
|
|
A double-free in the server could be triggered by an authenticated user if
|
|
dropbear is running with -a (Allow connections to forwarded ports from any host)
|
|
This could potentially allow arbitrary code execution as root by an authenticated user.
|
|
Affects versions 2013.56 to 2016.74. Thanks to Mark Shepard for reporting the crash.
|
|
CVE-2017-9078 https://secure.ucc.asn.au/hg/dropbear/rev/c8114a48837c
|
|
|
|
- Security: Fix information disclosure with ~/.ssh/authorized_keys symlink.
|
|
Dropbear parsed authorized_keys as root, even if it were a symlink. The fix
|
|
is to switch to user permissions when opening authorized_keys
|
|
|
|
A user could symlink their ~/.ssh/authorized_keys to a root-owned file they
|
|
couldn't normally read. If they managed to get that file to contain valid
|
|
authorized_keys with command= options it might be possible to read other
|
|
contents of that file.
|
|
This information disclosure is to an already authenticated user.
|
|
Thanks to Jann Horn of Google Project Zero for reporting this.
|
|
CVE-2017-9079 https://secure.ucc.asn.au/hg/dropbear/rev/0d889b068123
|
|
|
|
- Generate hostkeys with dropbearkey atomically and flush to disk with fsync
|
|
Thanks to Andrei Gherzan for a patch
|
|
|
|

|
|
Thanks to Henrik Nordström and Peter Krefting for patches.
|
|
|
|
2016.74 - 21 July 2016
|
|
|
|
- Security: Message printout was vulnerable to format string injection.
|
|
|
|
If specific usernames including "%" symbols can be created on a system
|
|
(validated by getpwnam()) then an attacker could run arbitrary code as root
|
|
when connecting to Dropbear server.
|
|
|
|
A dbclient user who can control username or host arguments could potentially
|
|
run arbitrary code as the dbclient user. This could be a problem if scripts
|
|
or webpages pass untrusted input to the dbclient program.
|
|
CVE-2016-7406
|
|
https://secure.ucc.asn.au/hg/dropbear/rev/b66a483f3dcb
|
|
|
|
- Security: dropbearconvert import of OpenSSH keys could run arbitrary code as
|
|
the local dropbearconvert user when parsing malicious key files
|
|
CVE-2016-7407
|
|
https://secure.ucc.asn.au/hg/dropbear/rev/34e6127ef02e
|
|
|
|
- Security: dbclient could run arbitrary code as the local dbclient user if
|
|
particular -m or -c arguments are provided. This could be an issue where
|
|
dbclient is used in scripts.
|
|
CVE-2016-7408
|
|
https://secure.ucc.asn.au/hg/dropbear/rev/eed9376a4ad6
|
|
|
|
- Security: dbclient or dropbear server could expose process memory to the
|
|
running user if compiled with DEBUG_TRACE and running with -v
|
|
CVE-2016-7409
|
|
https://secure.ucc.asn.au/hg/dropbear/rev/6a14b1f6dc04

|
|
|
|
- Reduce local data copying for improved efficiency. Measured 30%
|
|
increase in throughput for connections to localhost
|
|
|
|
- Forwarded TCP ports connect asynchronously and try all available addresses
|
|
(IPv4, IPv6, round robin DNS)
|
|
|
|
- Fix all compile warnings, many patches from Gaël Portay
|
|
Note that configure with -Werror may not be successful on some platforms (OS X)
|
|
and some configuration options may still result in unused variable
|
|
warnings.
|
|
|
|
- Use TCP Fast Open on Linux if available. Saves a round trip at connection
|
|
to hosts that have previously been connected.
|
|
Needs a recent Linux kernel and possibly "sysctl -w net.ipv4.tcp_fastopen=3"
|
|
Client side is disabled by default pending further compatibility testing
|
|
with networks and systems.
|
|
|
|
- Increase maximum command length to 9000 bytes
|
|
|
|
- Free memory before exiting, patch from Thorsten Horstmann. Useful for
|
|
Dropbear ports to embedded systems and for checking memory leaks
|
|
with valgrind. Only partially implemented for dbclient.
|
|
This is disabled by default, enable with DROPBEAR_CLEANUP in sysoptions.h
|
|
|
|
- DROPBEAR_DEFAULT_CLI_AUTHKEY setting now always prepends home directory unless
|
|
there is a leading slash (~ isn't treated specially)
|
|
|
|
- Fix small ECC memory leaks
|
|
|
|
- Tighten validation of Diffie-Hellman parameters, from Florent Daigniere of

|
|
enabled if required for old clients with DROPBEAR_SERVER_DELAY_ZLIB
|
|
|
|
- Default client key path ~/.ssh/id_dropbear
|
|
|
|

|
|
|
|
- Fix installing dropbear.8 in a separate build directory, from Like Ma
|
|
|
|
- Allow configure to succeed if libtomcrypt/libtommath are missing, from Elan Ruusamäe

|
|
|
|
- Minor bug fixes, a few issues found by Coverity scan
|
|
|
|
2014.66 - Thursday 23 October 2014
|
|
|
|
- Use the same keepalive handling behaviour as OpenSSH. This will work better
|
|
with some SSH implementations that have different behaviour with unknown
|
|
message types.
|
|
|
|
- Don't reply with SSH_MSG_UNIMPLEMENTED when we receive a reply to our own
|
|
keepalive message
|
|
|

|
|
others), thanks to NiLuJe for tracking it down
|
|
|
|
- Fix 2014.64 regression, clock_gettime() error handling which broke on older
|
|

|
|
|
|

|
|
|
|
2014.64 - Sunday 27 July 2014
|
|
|
|
- Fix compiling with ECDSA and DSS disabled
|
|
|
|
- Don't exit abruptly if too many outgoing packets are queued for writev(). Patch
|
|
thanks to Ronny Meeus
|
|
|
|
- The -K keepalive option now behaves more like OpenSSH's "ServerAliveInterval".
|
|
If no response is received after 3 keepalives then the session is terminated. This
|
|
will close connections faster than waiting for a TCP timeout.
|
|
|
|
- Rework TCP priority setting. New settings are
|
|
if (connecting || ptys || x11) tos = LOWDELAY
|
|
else if (tcp_forwards) tos = 0
|
|
else tos = BULK
|
|
Thanks to Catalin Patulea for the suggestion.
|
|
|
|
- Improve handling of many concurrent new TCP forwarded connections, should now
|
|
be able to handle as many as MAX_CHANNELS. Thanks to Eduardo Silva for reporting
|
|
and investigating it.
|
|
|
|
- Make sure that exit messages from the client are printed, regression in 2013.57
|
|
|
|
- Use monotonic clock where available, timeouts won't be affected by system time
|
|
changes
|
|
|
|
- Add -V for version
|
|
|
|
2014.63 - Wednesday 19 February 2014
|
|
|
|
- Fix ~. to terminate a client interactive session after waking a laptop
|
|
from sleep.
|
|
|
|
- Changed port separator syntax again, now using host^port. This is because
|
|
IPv6 link-local addresses use %. Reported by Gui Iribarren
|
|
|
|
- Avoid constantly relinking dropbearmulti target, fix "make install"
|
|
for multi target, thanks to Mike Frysinger
|
|
|
|
- Avoid getting stuck in a loop writing huge key files, reported by Bruno
|
|
Thomsen
|
|
|
|
- Don't link dropbearkey or dropbearconvert to libz or libutil,
|
|
thanks to Nicolas Boos
|
|
|
|
- Fix linking -lcrypt on systems without /usr/lib, thanks to Nicolas Boos
|
|
|
|
- Avoid crash on exit due to cleaned up keys before last packets are sent,
|
|
debugged by Ronald Wahl
|
|
|
|
- Fix a race condition in rekeying where Dropbear would exit if it received a
|
|
still-in-flight packet after initiating rekeying. Reported by Oliver Metz.
|
|
This is a longstanding bug but is triggered more easily since 2013.57
|
|
|
|
- Fix README for ecdsa keys, from Catalin Patulea
|
|
|
|
- Ensure that generated RSA keys are always exactly the length
|
|
requested. Previously Dropbear always generated N+16 or N+15 bit keys.
|
|
Thanks to Unit 193
|
|
|
|
- Fix DROPBEAR_CLI_IMMEDIATE_AUTH mode which saves a network round trip if the
|
|
first public key succeeds. Still not enabled by default, needs more
|
|
compatibility testing with other implementations.
|
|
|
|
- Fix for port 0 forwarding in the client and port forwarding with Apache MINA SSHD. Thanks to
|
|
|
|
- Fix for bad system linux/pkt-sched.h header file with older Linux
|
|
kernels, from Steve Dover
|
|
|
|
- Fix signal handlers so that errno is saved, thanks to Erik Ahlén for a patch
|
|
and Mark Wickham for independently spotting the same problem.
|
|
|
|
2013.62 - Tuesday 3 December 2013
|
|
|
|
- Disable "interactive" QoS connection options when a connection doesn't
|
|
have a PTY (eg scp, rsync). Thanks to Catalin Patulea for the patch.
|
|
|
|
- Log when a hostkey is generated with -R, fix some bugs in handling server
|
|
hostkey commandline options
|
|
|
|
- Fix crash in Dropbearconvert and 521 bit key, reported by NiLuJe
|
|
|
|
- Update config.guess and config.sub again
|
|
|
|
2013.61test - Thursday 14 November 2013
|
|
|
|
- Default generated RSA key size changed from 1024 to 2048 bits
|
|
|
|
- ECC (elliptic curve) support. Supports ECDSA hostkeys (requires new keys to
|
|
be generated) and ECDH for setting up encryption keys (no intervention
|
|
required). This is significantly faster.
|
|
|
|
- curve25519-sha256@libssh.org support for setting up encryption keys. This is
|
|
another elliptic curve mode with less potential of NSA interference in
|
|
algorithm parameters. curve25519-donna code thanks to Adam Langley
|
|
|
|
- -R option to automatically generate hostkeys. This is recommended for
|
|
embedded platforms since it allows the system random number device
|

|
|
|
|
- Disable client immediate authentication request by default, it prevents
|
|
passwordless logins from working
|
|
|
|
2013.57 - Monday 15 April 2013
|
|
|
|
- Decreased connection setup time particularly with high latency connections,
|
|
the number of round trips has been reduced for both client and server.
|
|
CPU time hasn't been changed.
|
|
|
|
- Client will send an initial key exchange guess to save a round trip.
|
|
Dropbear implements an extension kexguess2@matt.ucc.asn.au to allow the first
|
|
packet guess to succeed in wider circumstances than the standard behaviour.
|
|
When communicating with other implementations the standard behaviour is used.
|
|
|
|
- Client side: when public key or password authentication with
|
|
$DROPBEAR_PASSWORD is used an initial authentication request will
|
|
be sent immediately rather than querying the list of available methods.
|
|
This behaviour is enabled by CLI_IMMEDIATE_AUTH option (on by default),
|
|
please let the Dropbear author know if it causes any interoperability
|
|
problems.
|
|
|
|
- Implement client escape characters ~. (terminate session) and
|
|
~^Z (background session)
|
|
|
|
- Server will more reliably clean up utmp when connection is closed, reported by
|
|
Mattias Walström

- Allow a user in immediately if the account has a blank password and blank
|
|
passwords are enabled
|
|

- Client agent forwarding now works, using OpenSSH's ssh-agent
|
|
|
|
- Improve robustness of client multihop mode
|
|
|
|
- Fix a prime generation bug in bundled libtommath. This is unlikely to have
|
|
generated any bad keys in the wild.
|
|
See
|
|
https://bugzilla.redhat.com/show_bug.cgi?id=615088
|
|
http://bugs.gentoo.org/show_bug.cgi?id=328383
|
|
http://bugs.gentoo.org/show_bug.cgi?id=328409
|
|
|
|
- Attempt to build against system libtomcrypt/libtommath if available. This
|
|
can be disabled with ./configure --enable-bundled-libtom
|
|
|
|
- Make -K (keepalive) and -I (idle timeout) work together sensibly in the client.
|
|
The idle timeout is no longer reset by SSH_MSG_IGNORE packets.
|
|
|
|
- Add diffie-hellman-group14-sha1 key exchange method
|
|
|
|
- Compile fix if ENABLE_CLI_PROXYCMD is disabled
|
|
|
|
- /usr/bin/X11/xauth is now the default path
|
|
|
|
- Client remote forward (-L/-R) arguments now accept a listen address
|
|
|
|
- In uClinux avoid trashing the parent process when a session exits
|
|
|
|
- Blowfish is now disabled by default since it has large memory usage
|
|
|
|
- Add option to change zlib windowbits/memlevel. Use less memory by default
|
|
|
|
- DROPBEAR_SMALL_CODE is now disabled by default
|
|
|
|
- SSH_ORIGINAL_COMMAND environment variable is set by the server when an
|
|
authorized_keys command is specified.
|
|
|
|
- Set SSH_TTY and SSH_CONNECTION environment variables in the server
|
|
|
|
- Client banner is now printed to standard error rather than standard output
|
|
|
|
- Capitalisation in many log messages has been made consistent. This may affect
|
|
scripts that parse logfiles.
|
|
|
|
0.52 - Wed 12 November 2008
|
|
|
|
- Add "netcat-alike" option (-B) to dbclient, allowing Dropbear to tunnel
|
|
standard input/output to a TCP port-forwarded remote host.
|
|
|
|
- Add "proxy command" support to dbclient, to allow using a spawned process for
|
|
IO rather than a direct TCP connection. eg
|
|
dbclient remotehost
|
|
is equivalent to
|
|
dbclient -J 'nc remotehost 22' remotehost
|
|
(the hostname is still provided purely for looking up saved host keys)
|
|
|
|
- Combine netcat-alike and proxy support to allow "multihop" connections, with
|
|
comma-separated host syntax. Allows running
|
|
|
|
dbclient user1@host1,user2@host2,user3@host3
|
|
|
|
to end up at host3 via the other two, using SSH TCP forwarding. It's a bit
|
|
like onion-routing. All connections are established from the local machine.
|
|
The comma-separated syntax can also be used for scp/rsync, eg
|
|
|
|
rsync -a -e dbclient m@gateway,m2@host,martello:/home/matt/ ~/backup/
|
|
|
|
to bounce through a few hosts.
|
|
|
|
- Add -I "idle timeout" option (contributed by Farrell Aultman)
|
|
|
|
- Allow restrictions on authorized_keys logins such as restricting commands
|
|
to be run etc. This is a subset of those allowed by OpenSSH, doesn't
|
|
yet allow restricting source host.
|
|
|
|
- Use vfork() for scp on uClinux
|
|
|
|
- Default to PATH=/usr/bin:/bin for shells.
|
|
|
|
- Report errors if -R forwarding fails
|
|
|
|
- Add counter mode cipher support, which avoids some security problems with the
|
|
standard CBC mode.
|
|
|
|
- Support zlib@openssh.com delayed compression for client/server. It can be
|
|
required for the Dropbear server with the '-Z' option. This is useful for
|
|
security as it avoids exposing the server to attacks on zlib by
|
|
unauthenticated remote users, though requires client side support.
|
|
|
|
- options.h has been split into options.h (user-changable) and sysoptions.h
|
|
(less commonly changed)
|
|
|
|
- Support "dbclient -s sftp" to specify a subsystem
|
|
|
|
- Fix a bug in replies to channel requests that could be triggered by recent
|
|
versions of PuTTY
|
|
|
|
0.51 - Thu 27 March 2008
|
|
|
|
- Make a copy of password fields rather erroneously relying on getwpnam()
|
|
to be safe to call multiple times
|
|
|
|
- If $SSH_ASKPASS_ALWAYS environment variable is set (and $SSH_ASKPASS is
|
|
as well) always use that program, ignoring isatty() and $DISPLAY
|
|
|
|
- Wait until a process exits before the server closes a connection, so
|
|
that an exit code can be sent. This fixes problems with exit codes not
|
|
being returned, which could cause scp to fail.
|
|
|
|
0.50 - Wed 8 August 2007
|
|
|
|
- Add DROPBEAR_PASSWORD environment variable to specify a dbclient password
|
|
|
|
- Use /dev/urandom by default, since that's what everyone does anyway
|
|
|
|
- Correct vfork() use for uClinux in scp
|
|
(thanks to Alex Landau)
|
|
|
|
- Exit with an exit code of 1 if dropbear can't bind to any ports
|
|
(thanks to Nicolai Ehemann)
|
|
|
|
- Improve network performance and add a -W <receive_window> argument for
|
|
adjusting the tradeoff between network performance and memory consumption.
|
|
|
|
- Fix a problem where reply packets could be sent during key exchange,
|
|
in violation of the SSH spec. This could manifest itself with connections
|
|
being terminated after 8 hours with new TCP-forward connections being
|
|
established.
|
|
|
|
- Add -K <keepalive_time> argument, ensuring that data is transmitted
|
|
over the connection at least every N seconds.
|
|
|
|
- dropbearkey will no longer generate DSS keys of sizes other than 1024
|
|
bits, as required by the DSS specification. (Other sizes are still
|
|
accepted for use to provide backwards compatibility).
|
|
|
|
0.49 - Fri 23 February 2007
|
|
|
|
- Security: dbclient previously would prompt to confirm a
|
|
mismatching hostkey but wouldn't warn loudly. It will now
|
|
exit upon a mismatch. CVE-2007-1099
|
|
|
|
- Compile fixes, make sure that all variable definitions are at the start
|
|
of a scope.
|
|
|
|
- Added -P pidfile argument to the server (from Swen Schillig)
|
|
|
|
- Add -N dbclient option for "no command"
|
|
|
|
- Add -f dbclient option for "background after auth"
|
|
|
|
- Add ability to limit binding to particular addresses, use
|
|
-p [address:]port, patch from Max-Gerd Retzlaff.
|
|
|
|
- Try to finally fix ss_family compilation problems (for old
|
|
glibc systems)
|
|
|
|
- Fix finding relative-path server hostkeys when running daemonized
|
|
|
|
- Use $HOME in preference to that from /etc/passwd, so that
|
|
dbclient can still work on broken systems.
|
|
|
|
- Fix various issues found by Klocwork defect analysis, mostly memory leaks
|
|
and error-handling. Thanks to Klocwork for their service.
|
|
|
|
- Improve building in a separate directory
|
|
|
|
- Add compile-time LOG_COMMANDS option to log user commands
|
|
|
|
- Add '-y' flag to dbclient to unconditionally accept host keys,
|
|
patch from Luciano Miguel Ferreira Rocha
|
|
|
|
- Return immediately for "sleep 10 & echo foo", rather than waiting
|
|
for the sleep to return (pointed out by Rob Landley).
|
|
|
|
- Avoid hanging after exit in certain cases (such as scp)
|
|
|
|
- Various minor fixes, in particular various leaks reported by
|
|
Erik Hovland
|
|
|
|
- Disable core dumps on startup
|
|
|
|
- Don't erase over every single buffer, since it was a bottleneck.
|
|
On systems where it really matters, encrypted swap should be utilised.
|
|
|
|
- Read /dev/[u]random only once at startup to conserve kernel entropy
|
|
|
|
- Upgrade to LibTomCrypt 1.16 and LibTomMath 0.40

|
|
(thanks to Tomas Vanek for helping track it down)
|
|
|
|
- Implement per-IP pre-authentication connection limits
|
|
(after some poking from Pablo Fernandez) CVE-2006-1206

|
- Exit gracefully if trying to connect to as SSH v1 server
|
|
(reported by Rushi Lala)
|
|
|
|
- Only read /dev/random once at startup when in non-inetd mode

|
|
|
- Merged in uClinux patch for inetd mode
|
|
|
|
- Updated to scp from OpenSSH 4.3p2 - fixes a security issue
|
|
where use of system() could cause users to execute arbitrary
|
|
code through malformed filenames, ref CVE-2006-0225
|
|
|
|
0.47 - Thurs Dec 8 2005
|
|
|
|
- SECURITY: fix for buffer allocation error in server code, could potentially
|
|
allow authenticated users to gain elevated privileges. All multi-user systems

|
|
- Avoid a race in server shell-handling code which prevents the exit-code
|
|
from being returned to the client in some circumstances.
|
|
|
|
- Makefile modified so that install target works correctly (doesn't try
|
|
to install "all" binary) - patch from Juergen Daubert
|
|
|
|
- Various minor fixes and compile warnings.
|
|
|
|
0.44test4 - Tue Sept 14 2004 21:15:54 +0800
|
|
|
|
- Fix inetd mode so it actually loads the hostkeys (oops)
|
|
|
|
- Changed DROPBEAR_DEFPORT properly everywhere
|
|
|
|
- Fix a small memory leak in the auth code
|
|
|
|
- WCOREDUMP is only used on systems which support it (ie not cygwin or AIX)
|
|
|
|
- Check (and fail for) cases when we can't negotiate algorithms with the
|
|
remote side successfully (rather than bombing out ungracefully)
|
|
|
|
- Handle authorized_keys files without a terminating newline
|
|
|
|
- Fiddle the channel receive window size for possibly better performance
|
|
|
|
- Added in the PAM authentication code (finally! thanks to Martin Carlsson)
|
|
|
|
0.44test3 - Fri Aug 27 22:20:54 +0800
|
|
|
|
- Fixed a bunch of warnings.
|
|
|
|
- scp works correctly when passed a username (fix for the dbclient program
|
|
itself as well, "-lmatt" works as well as "-l matt").
|
|
|
|
- Remove unrequired debian files
|
|
|
|
- Exit with the remote process's return code for dbclient
|
|
|
|
- Display stderr messages from the server in the client
|
|
|
|
- Add circular buffering to the channel code. This should dramatically reduce
|
|
the amount of backtraffic sent in response to traffic incoming to the
|
|
Dropbear end - improves high-latency performance (ie dialup).
|
|
|
|
- Various other related channel-handling fixups.
|
|
|
|
- Allow leading lines in the banner when connecting to servers
|
|
|
|
- Fixed printing out errors onto the network socket with stderr (for inetd
|
|
mode when using xinetd)
|
|
|
|
- Remove obselete documentation
|
|
|
|
- Fix a null-pointer exception when trying to free non-existant listeners
|
|
at cleanup.
|
|
|
|
- DEBUG_TRACE now only works if you add "-v" to the program commandline
|
|
|
|
- Don't leave stdin non-blocking on exit - this caused the parent shell
|
|
of dbclient to close when dbclient exited, for some shells in BusyBox
|
|
|
|
- Server connections no longer timeout after 5 minutes
|
|
|
|
- Fixed stupid DSS hostkey typo (server couldn't load host keys)
|
|
|
|
0.44test2 - Tues Aug 17 2004 17:43:54 +0800
|
|
|
|
- Fix up dropbearmulti targets in the Makefile - symlinks are now created
|
|
|
|
- Compile fake-rfc2553 even with dropbearconvert/dropbearkey - this
|
|
allows them to work on platforms without a native getaddrinfo()
|
|
|
|
- Create ~/.ssh/known_hosts properly if it doesn't exist
|
|
|
|
- Fix basename() function prototype
|
|
|
|
- Backport some local changes (more #ifdefs for termcodes.c, a fix for missing
|
|
defines on AIX).
|
|
|
|
- Let dbclient be run as "ssh"
|
|
|
|
- Initialise mp_ints by default
|
|
|
|
0.44test1 - Sun Aug 16 2005 17:43:54 +0800
|
|
|
|
- TESTING RELEASE - this is the first public release of the client codebase,
|
|
so there are sure to be bugs to be found. In addition, if you're just using
|
|
the server portion, the final binary size probably will increase - I'll
|
|
be trying to get it back down in future releases.
|
|
|
|
- Dropbear client added - lots of changes to the server code as well to
|
|
generalise things
|
|
|
|
- IPv6 support added for client, server, and forwarding
|
|
|
|
- New makefile with more generic support for multiple-program binaries
|
|
|
|
0.43 - Fri Jul 16 2004 17:44:54 +0800
|
|
|
|
- SECURITY: Don't try to free() uninitialised variables in DSS verification
|
|
code. Thanks to Arne Bernin for pointing out this bug. This is possibly
|
|
exploitable, all users with DSS and pubkey-auth compiled in are advised to
|
|
upgrade. CVE-2004-2486
|
|
|
|
- Clean up agent forwarding socket files correctly, patch from Gerrit Pape.
|
|
|
|
- Don't go into an infinite loop when portforwarding to servers which don't
|
|
send any initial data/banner. Patch from Nikola Vladov
|
|
|
|
- Fix for network vs. host byte order in logging remote TCP ports, also
|
|
from Gerrit Pape.
|
|
|
|
- Initialise many pointers to NULL, for general safety. Also checked cleanup
|
|
code for mp_ints (related to security issues above).
|
|
|
|
0.42 - Wed Jun 16 2004 12:44:54 +0800
|
|
|
|
- Updated to Gerrit Pape's official Debian subdirectory
|
|
|
|
- Fixed bad check when opening /dev/urandom - thanks to Danny Sung.
|
|
|
|
- Added -i inetd mode flag, and associated options in options.h . Dropbear
|
|
can be compiled with either normal mode, inetd, or both modes. Thanks
|
|
to Gerrit Pape for basic patch and motivation.
|
|
|
|
- Use <dirent.h> rather than <sys/dir.h> for POSIX compliance. Thanks to Bill
|
|
Sommerfield.
|
|
|
|
- Fixed a TCP forwarding (client-local, -L style) bug which caused the whole
|
|
session to close if the TCP connection failed. Thanks to Andrew Braund for
|
|
reporting it and helping track it down.
|
|
|
|
- Re-enable sigpipe for child processes. Thanks to Gerrit Pape for some
|
|
suggestions, and BSD manpages for a clearer explanation of the behaviour.
|
|
|
|
- Added manpages, thanks to Gerrit Pape.
|
|
|
|
- Changed license text for LibTomCrypt and LibTomMath.
|
|
|
|
- Added strip-static target
|
|
|
|
- Fixed a bug in agent-forwarding cleanup handler - would segfault
|
|
(dereferencing a null pointer) if agent forwarding had failed.
|
|
|
|
- Fix behaviour of authorized_keys parsing, so larger (>1024 bit) DSA keys will
|
|
work. Thanks to Dr. Markus Waldeck for the report.
|
|
|
|
- Fixed local port forwarding code so that the "-j" option will make forwarding
|
|
attempts fail more gracefully.
|
|
|
|
- Allow repeated requests in a single session if previous ones fail - this fixes PuTTY and some other SCP clients, which try SFTP, then fall-back to SCP if it
|
|
isn't available. Thanks to Stirling Westrup for the report.
|
|
|
|
- Updated to LibTomCrypt 0.96 and LibTomMath 0.30. The AES code now uses
|
|
smaller non-precomputed tables if DROPBEAR_SMALL_CODE is defined in
|
|
options.h, leading to a significant reduction in the binary size.
|
|
|
|
0.41 - Mon Jan 19 2004 22:40:19 +0800
|
|
|
|
- Fix in configure so that cross-compiling works, thanks to numerous people for
|
|
reporting and testing
|
|
|
|
- Terminal mode parsing now handles empty terminal mode strings (sent by
|
|
Windows ssh.com clients), thanks to Ricardo Derbes for the report
|
|
|
|
- Handling is improved for users with no shell specified in /etc/passwd,
|
|
thanks again to Ricardo Derbes
|
|
|
|
- Fix for compiling with --disable-syslog, thanks to gordonfh
|
|
|
|
- Various minor fixes allow scp to work with irix, thanks to Paul Marinceu for
|
|
fixing it up
|
|
|
|
- Use <stropts.h> not <sys/stropts.h>, since the former seems more common
|
|
|
|

|
|
pointing that out).

|
|
use fgetc not getc to avoid strange macro-related issues), thanks to

|
|
when forwarding X11 connections.
|
|
- Add dropbearconvert to convert to/from OpenSSH host keys and Dropbear keys

|
Grahame (grahame at angrygoats.net)
|
|
- 'install' target added to the makefile
