paramiko/paramiko#2337 which is already in references. This advisory probably should be rewritten to not be Russh specific (CVE-2023-48795 is an issue affecting a lot of libraries, and in fact GitHub already acknowledges it affects golang.org/x/crypto).

See also: #2869.

Many thanks for the call out. I've done a quick genericization of the advisory, but kept a bunch of the detail. 👍
