Summary
Security update for ssh-audit

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.
