The git2 and libgit2-sys crates are Rust wrappers around the
libgit2 C library. It was discovered that libgit2 1.5.0
and below did not verify SSH host keys when establishing an SSH connection,
exposing users of the library to Man-In-the-Middle attacks.
The libgit2 team assigned CVE-2023-22742 to this
vulnerability. The following versions of the libgit2-sys Rust crate have been
released:
A new git2 crate version has also been released, 0.16.1. This version only
bumps its libgit2-sys dependency to ensure no vulnerable libgit2-sys versions
are used, but contains no code changes: if you update the libgit2-sys version
there is no need to also update the git2 crate version.
