QID 996375: Rust (Rust) Security Update for golang.org/x/crypto (GHSA-45x7-px36-x8w8)

Russh v0.40.1 and earlier is vulnerable to a novel prefix truncation attack (a.k.a. Terrapin attack), which allows a man-in-the-middle attacker to strip an arbitrary number of messages right after the initial key exchange, breaking SSH extension negotiation (RFC8308) in the process and thus downgrading connection security.

Successful exploitation of this vulnerability could lead to a security breach or could affect integrity, availability, and confidentiality.
