Debian Bug : 1144465
Multiple security issues were discovered in libgit2, a low-level Git
library, which could result in the execution of arbitrary commands on a
remote SSH server, disclosure of credentials, denial of service or the
creation of directories outside a repository's working tree.
For the stable distribution (trixie), these problems have been fixed in
version 1.9.0+ds-2+deb13u1.
We recommend that you upgrade your libgit2 packages.
For the detailed security status of libgit2 please refer to
