openSUSE-SU-2021:1383-1

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
  • AEADAES128_GCM
  • AEADAES256_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, AEADAES128GCM, AEADAES256GCM, crypticore128@ssh.com, seed-cbc@ssh.com.
• Added 3 new MACs: chacha20-poly1305@openssh.com, hmac-sha3-224, crypticore-mac@ssh.com.
• Update ssh-audit.keyring
