Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Apache MINA SSHD (sshd-common) versions before 2.12.0 are affected by a Terrapin-style integrity check bypass. An attacker able to intercept traffic between client and server can drop certain packets, which may leave the connection with some security features downgraded or disabled. Upgrade to version 2.12.0 or later, and note that both the client and server sides need the fix, since an unpatched peer may still leave the connection affected.
