Description:

KVM was updated to fix the following security issues:

could be used to carry out denial of service attacks or potential
code execution against the host. This vulnerability is also known as
VENOM.
* CVE-2014-0222: Integer overflow in the qcow_open function in
block/qcow.c in QEMU allowed remote attackers to cause a denial of
service (crash) via a large L2 table in a QCOW version 1 image.
* CVE-2014-0223: Integer overflow in the qcow_open function in
block/qcow.c in QEMU allowed 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.
