GLSA-201309-18 : libvirt: Multiple vulnerabilities

This script is Copyright (C) 2013-2015 Tenable Network Security, Inc.

Synopsis :

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

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.

# emerge --ask --oneshot --verbose
