Notes
Title of the patch
Security update for ssh-audit
Description of the patch
This update for ssh-audit fixes the following issues:
ssh-audit was updated to version 2.5.0
* Fixed crash when running host key tests.
* Handles server connection failures more gracefully.
* Now prints JSON with indents when -jj is used (useful for
debugging).
* Added MD5 fingerprints to verbose output.
* Added -d/--debug option for getting debugging output.
* Updated JSON output to include MD5 fingerprints. Note that
this results in a breaking change in the 'fingerprints'
dictionary format.
* Updated OpenSSH 8.1 (and earlier) policies to include
rsa-sha2-512 and rsa-sha2-256.
* Added OpenSSH v8.6 & v8.7 policies.
* Added 3 new key exchanges:
+ gss-gex-sha1-eipGX3TCiQSrx573bT1o1Q==
+ gss-group1-sha1-eipGX3TCiQSrx573bT1o1Q==
+ gss-group14-sha1-eipGX3TCiQSrx573bT1o1Q==
* Added 3 new MACs:
+ hmac-ripemd160-96
+ AEAD_AES_128_GCM
+ AEAD_AES_256_GCM
Update to version 2.4.0
* Added multi-threaded scanning support.
* Added version check for OpenSSH user enumeration (CVE-2018-15473).
* Added deprecation note to host key types based on SHA-1.
* Added extra warnings for SSHv1.
* Added built-in hardened OpenSSH v8.5 policy.
* Upgraded warnings to failures for host key types based on SHA-1
* Fixed crash when receiving unexpected response during host key
test.
* Fixed hang against older Cisco devices during host key test &
gex test.
* Fixed improper termination while scanning multiple targets when
one target returns an error.
* Dropped support for Python 3.5 (which reached EOL in Sept.2020)
* Added 1 new key exchange: sntrup761x25519-sha512@openssh.com.
Update to version 2.3.1
* Now parses public key sizes for
rsa-sha2-256-cert-v01@openssh.com and
rsa-sha2-512-cert-v01@openssh.com host key types.
* Flag ssh-rsa-cert-v01@openssh.com as a failure due to SHA-1
hash.
* Fixed bug in recommendation output which suppressed some
algorithms inappropriately.
* Built-in policies now include CA key requirements (if
certificates are in use).
* Lookup function (--lookup) now performs case-insensitive
lookups of similar algorithms.
* Migrated pre-made policies from external files to internal
database.
* Split single 3,500 line script into many files (by class).
* Added setup.py support
* Added 1 new cipher: des-cbc@ssh.com.
Update to version 2.3.0
The highlight of this release is support for policy scanning
(this allows an admin to test a server against a
hardened/standard configuration).
* Added new policy auditing functionality to test adherence to
a hardening guide/standard configuration
(see -L/--list-policies, -M/--make-policy and -P/--policy).
* Created new man page (see ssh-audit.1 file).
* 1024-bit moduli upgraded from warnings to failures.
* Many Python 2 code clean-ups, testing framework improvements,
pylint & flake8 fixes, and mypy type comments.
* Added feature to look up algorithms in internal database
(see --lookup)
* Suppress recommendation of token host key types.
* Added check for use-after-free vulnerability in PuTTY v0.73.
* Added 11 new host key types: ssh-rsa1, ssh-dss-sha256@ssh.com,
ssh-gost2001, ssh-gost2012-256, ssh-gost2012-512,
spki-sign-rsa, ssh-ed448, x509v3-ecdsa-sha2-nistp256,
x509v3-ecdsa-sha2-nistp384, x509v3-ecdsa-sha2-nistp521,
x509v3-rsa2048-sha256.
* Added 8 new key exchanges: diffie-hellman-group1-sha256,
kexAlgoCurve25519SHA256, Curve25519SHA256, gss-group14-sha256-,
gss-group15-sha512-, gss-group16-sha512-, gss-nistp256-sha256-,
gss-curve25519-sha256-.
* Added 5 new ciphers: blowfish, AEAD_AES_128_GCM,
AEAD_AES_256_GCM, crypticore128@ssh.com, seed-cbc@ssh.com.
* Added 3 new MACs: chacha20-poly1305@openssh.com, hmac-sha3-224,
crypticore-mac@ssh.com.
