GHSA-4R3C-5HPG-58QR Russh SSH message fields were decoded through allocation-first parsers before field-specific bounds

SSH message fields were decoded through allocation-first parsers before field-specific bounds Summary Several russh client and server message handlers decoded attacker-controlled SSH strings, name-lists, and byte fields into owned allocations before applying field-specific bounds. A remote SSH pe...

Summary russh did not enforce the SSH identification-string rules as deliberately as OpenSSH. In particular, the server-side identification reader used the same permissive path as the client, allowing pre-banner lines from clients, and the reader did not enforce a bounded number of pre-banner...
