Several security issues were fixed in libarchive.

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
