Scientific Linux Security Update : libvirt on SL7.x x86_64

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


Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

The following packages have been upgraded to a newer upstream version:
libvirt (2.0.0).

Security Fix(es) :

- It was found that the libvirt daemon, when using RBD
(RADOS Block Device), leaked private credentials to the
process list. A local attacker could use this flaw to
perform certain privileged operations within the
cluster. (CVE-2015-5160)

- A path-traversal flaw was found in the way the libvirt
daemon handled filesystem names for storage volumes. A
libvirt user with privileges to create storage volumes
and without privileges to create and modify domains
could possibly use this flaw to escalate their
privileges. (CVE-2015-5313)

- It was found that setting a VNC password to an empty
string in libvirt did not disable all access to the VNC
server as documented, instead it allowed access with no
authentication required. An attacker could use this flaw
to access a VNC server with an empty VNC password
without any authentication. (CVE-2016-5008)
