Scientific Linux Security Update : libvirt on SL5.x i386/x86_64

This script is Copyright (C) 2012 Tenable Network Security, Inc.


Synopsis :

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

Description :

The libvirtd daemon was discovered to not properly check user
connection permissions before performing certain privileged actions,
such as requesting migration of an unprivileged guest domain to
another system. A local user able to establish a read-only connection
to libvirtd could use this flaw to perform actions that should be
restricted to read-write connections. (CVE-2008-5086)

libvirt_proxy, a setuid helper application allowing non-privileged
users to communicate with the hypervisor, was discovered to not
properly validate user requests. Local users could use this flaw to
cause a stack-based buffer overflow in libvirt_proxy, possibly
allowing them to run arbitrary code with root privileges.
(CVE-2009-0036)

After installing the update, libvirtd must be restarted manually (for
example, by issuing a 'service libvirtd restart' command) for this
change to take effect.
