    Package        : libgit2     CVE ID         : CVE-2026-5917 CVE-2026-53583 CVE-2026-53584 CVE-2026-53585                      CVE-2026-53586 CVE-2026-53587     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     its security tracker page at:
