   An update that fixes three vulnerabilities is now
   available. It includes one version update.

Description:


   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.

   Security Issues:

       * CVE-2015-3456
         
       * CVE-2014-0222
