{"id":"CVE-2026-5121","state":"PUBLISHED","title":"Libarchive: libarchive: arbitrary code execution via integer overflow in iso9660 image processing","description":"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.","publishedAt":"2026-03-30T07:47:28.562Z","updatedAt":"2026-10-14T19:24:20.226Z","severity":{"score":7.5,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","source":"redhat"},"assigner":"redhat","products":["Red
