GLSA-201309-18 : libvirt: Multiple vulnerabilities

This script is Copyright (C) 2013-2014 Tenable Network Security, Inc.


Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-201309-18
(libvirt: Multiple vulnerabilities)

An error in the virNetMessageFree() function in rpc/virnetserverclient.c
can lead to a use-after-free. Additionally, a socket leak in the
remoteDispatchStoragePoolListAllVolumes command can lead to file
descriptor exhaustion.

Impact :

A remote attacker could cause certain errors during an RPC connection to
cause a message to be freed without being removed from the message queue,
possibly resulting in execution of arbitrary code or a Denial of Service
condition. Additionally, a remote attacker could repeatedly issue the
command to list all pool volumes, causing a Denial of Service condition.

Workaround :

There is no known workaround at this time.

Solution :

All libvirt users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose
'>=app-emulation/libvirt-1.0.5.1-r3'

Risk factor :

High / CVSS Base Score : 9.3
