KVM was updated to fix the following security issues:

   * CVE-2015-3456: Buffer overflow in the floppy drive emulation, which
     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.
