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.","state":"PUBLISHED","assigner":"redhat","published_at":"2026-03-30 08:16:18","updated_at":"2026-10-14
