CVE-2014-0223 – Qemu: qcow1: validate image size to avoid out-of-bounds memory access

https://notcve.org/view.php?id=CVE-2014-0223

Integer overflow in the qcow_open function in block/qcow.c in QEMU before 1.7.2 allows local users to cause a denial of service (crash) and possibly execute arbitrary code via a large image size, which triggers a buffer overflow or out-of-bounds read. Desbordamiento de enteros en la función qcow_open en block/qcow.c en QEMU anterior a 1.7.2 permite a usuarios locales causar una denegación de servicio (caída) y posiblemente ejecutar código arbitrario a través de un tamaño grande de imagen, lo que provoca un desbordamiento de buffer o una lectura fuera de rango. 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.nongnu.org/archive/html/qemu-stable/2014-07/msg00187.html http://lists.opensuse.org/opensuse-security-announce/2015-05/msg00021.html http://www.debian.org/security/2014/dsa-3044 http://www.securityfocus.com/bid/67391 https://lists.gnu.org/archive/html/qemu-devel/2014-05/msg02156.html https://access.redhat.com/security/cve/CVE-2014-0223 https://bugzilla.redhat.com/show_bug.cgi?id=1097222 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-189: Numeric Errors •
