CVE-2014-0222 – Qemu: qcow1: validate L2 table size to avoid integer overflows
https://notcve.org/view.php?id=CVE-2014-0222
Integer overflow in the qcow_open function in block/qcow.c in QEMU before 1.7.2 allows remote attackers to cause a denial of service (crash) via a large L2 table in a QCOW version 1 image. Desbordamiento de enteros en la función qcow_open en block/qcow.c en QEMU anterior a 1.7.2 permite a atacantes remotos causara una denegación de servicio (caída) a través de una tabla L2 grande en un imagen QCOW versión 1. An integer overflow flaw was found in the QEMU block driver for QCOW version 1 disk images. A user able to alter the QEMU disk image files loaded by a guest could use this flaw to corrupt QEMU process memory on the host, which could potentially result in arbitrary code execution on the host with the privileges of the QEMU process. • http://lists.fedoraproject.org/pipermail/package-announce/2014-June/134053.html http://lists.fedoraproject.org/pipermail/package-announce/2014-May/133345.html http://lists.nongnu.org/archive/html/qemu-stable/2014-07/msg00187.html http://lists.opensuse.org/opensuse-security-announce/2015-05/msg00021.html http://lists.opensuse.org/opensuse-updates/2015-11/msg00063.html http://www.debian.org/security/2014/dsa-3044 http://www.securityfocus.com/bid/67357 https://lists.gnu.org/archive/html/qemu • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-189: Numeric Errors •
