- Fixed buffer overflow in build_plain() function
- Fixed buffer overflow in mp_add_cs_buf() function
- Fixed copy/paste error leading to invalid "Integer overflow detected in keyspace of mask" in attack-mode 6 and 7
- Fixed calculation of brain-session ID, only the first hash of the hashset was taken into account
- Fixed cleanup of password candidate buffers on GPU set from autotune in case -n was used
- Fixed copy/paste error leading to invalid "Integer overflow detected in keyspace of mask" in attack-mode 6 and 7
- Fixed cracking multiple Office hashes (modes 9500, 9600) with the same salt
- Fixed cracking of Blockchain, My Wallet (V1 and V2) hashes with unexpected decrypted data
- Fixed cracking of Cisco-PIX and Cisco-ASA MD5 passwords in mask-attack mode if mask > length 16

- Fixed race condition in maskfile mode by using a dedicated flag for restore execution
- Fixed some memory leaks in case hashcat is shutting down due to some file error
- Fixed some memory leaks in case mask-files are used in optimized mode
- Fixed --status-json to correctly escape certain characters in hashes
- Fixed the 7-Zip parser to allow the entire supported range of encrypted and decrypted data lengths
- Fixed the validation of the --brain-client-features command line argument (only values 1, 2 or 3 are allowed)
- Fixed --status-json to correctly escape certain characters in hashes
