This script is Copyright (C) 2015-2016 Tenable Network Security, Inc.


Synopsis :

The remote SUSE host is missing one or more security updates.

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.

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
