Summary
dpkg vulnerability
Details

Yashashree Gund discovered that the dpkg dpkg-deb tool incorrectly handled certain zstd-compressed .deb archives. If a user or automated system were tricked into manipulating a specially crafted .deb archive, a remote attacker could possibly use this issue to cause dpkg-deb to stop responding, resulting in a denial of service.
