NVD Description

Note: Versions mentioned in the description apply only to the upstream libarchive-doc package and not the libarchive-doc package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

A flaw was found in libarchive. On 32-bit systems, an integer overflow vulnerability exists in the zisofs block pointer allocation logic. A remote attacker can exploit this by providing a specially crafted ISO9660 image, which can lead to a heap buffer overflow. This could potentially allow for arbitrary code execution on the affected system.
