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.
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.
