Full runtime dependencies of erts-17.0.5

kernel-9.0, sasl-3.3, stdlib-4.1

ssh-6.0.4

The ssh-6.0.4 application can be applied independently of other applications on a full OTP 29 installation.

Fixed Bugs and Malfunctions

  • The SSH client and server now reject incoming packets not aligned to the cipher block size as required by RFC 4253 §6. For CBC ciphers, a timing-safe "packet discard" mechanism (CVE-2008-5161 mitigation) ensures structural errors are indistinguishable from MAC failures before disconnecting. AEAD and encrypt-then-MAC modes disconnect immediately.
