CVE-2026-48107 · Russh: Unchecked keyboard-interactive prompt count in client auth path
Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.
Russh is a Rust SSH client & server library. From version 0.37.0 to before version 0.61.0, in the russh client keyboard-interactive authentication path, a malicious SSH server could send a USERAUTH_INFO_REQUEST with an attacker-controlled prompt count, and the client would use that raw count directly in Vec::with_capacity(...) before validating that enough prompt data was actually present in the packet. This issue has been patched in version 0.61.0.
