#
|
||||
# Description:
|
||||
#
|
||||
# Modern Linux distributions offer some mitigation techniques to make it
|
||||
# harder to exploit software vulnerabilities reliably. Mitigations such
|
||||
# as RELRO, NoExecute (NX), Stack Canaries, Address Space Layout
|
||||
# Randomization (ASLR) and Position Independent Executables (PIE) have
|
||||
# made reliably exploiting any vulnerabilities that do exist far more
|
||||
# challenging. The checksec.sh script is designed to test what *standard*
|
||||
# Linux OS and PaX (http://pax.grsecurity.net/) security features are being
|
||||
# used.
|
||||
#
|
||||
# As of version 1.3 the script also lists the status of various Linux kernel
|
||||
# protection mechanisms.
|
||||

|
||||

# Thanks to Brad Spengler (grsecurity.net) for the PaX support.
