Details

It was discovered that the libarchive bsdunzip utility incorrectly handled
certain ZIP archive files. If a user or automated system were tricked into
processing a specially crafted ZIP archive, an attacker could use this
issue to cause libarchive to crash, resulting in a denial of service, or
possibly execute arbitrary code. This issue only affected Ubuntu 24.04 LTS,
Ubuntu 24.10, and Ubuntu 25.04. (CVE-2025-1632)

It was discovered that libarchive incorrectly handled certain TAR archive

libarchive to crash, resulting in a denial of service, or possibly execute
arbitrary code. (CVE-2025-25724)
