==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 25.04
- Ubuntu 24.10
- Ubuntu 24.04 LTS
- Ubuntu 22.04 LTS

Summary:

Several security issues were fixed in libarchive.

Software Description:
- libarchive: Library to read/write archive files

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
files. If a user or automated system were tricked into processing a
specially crafted TAR archive, an attacker could use this issue to cause
libarchive to crash, resulting in a denial of service, or possibly execute
arbitrary code. (CVE-2025-25724)
