GHSA-G9HV-X236-4QP3 Russh: client wrong-length X25519 `clone_from_slice` panic (pre-auth DoS)

Summary A malicious SSH server can crash a russh client session with a single malformed key-exchange reply, causing a pre-authentication Denial-of-Service before the server host key is verified. The embedding process itself stays up, but the connection is killed deterministically. Details Every...

Russh: Pre-auth remote panic via all-zero Curve25519 peer public value (encode_mpint OOB)

A pre-authentication denial-of-service panic in russh 0.62.2 commit c4be19f1915c8682f4615c3fd50008512b474491, current default branch main as of 2026-07-22.
