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


Synopsis :

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

Description :

xen was updated to fix eight security issues.

These security issues were fixed :

- CVE-2015-4037: The slirp_smb function in net/slirp.c
created temporary files with predictable names, which
allowed local users to cause a denial of service
(instantiation failure) by creating /tmp/qemu-smb.*-*
files before the program (bsc#932267).

- CVE-2014-0222: Integer overflow in the qcow_open
function allowed remote attackers to cause a denial of
service (crash) via a large L2 table in a QCOW version 1
image (bsc#877642).

- CVE-2015-7835: Uncontrolled creation of large page
mappings by PV guests (bsc#950367).

- CVE-2015-5239: Integer overflow in vnc_client_read() and
protocol_client_msg() (bsc#944463).

- CVE-2015-6815: With e1000 NIC emulation support it was
possible to enter an infinite loop (bsc#944697).

- CVE-2015-7969: Leak of main per-domain vcpu pointer
array leading to denial of service (bsc#950703).

- CVE-2015-7969: Leak of per-domain profiling- related
vcpu pointer array leading to denial of service
(bsc#950705).

- CVE-2015-7971: Some pmu and profiling hypercalls log
without rate limiting (bsc#950706).

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.
