GLSA-201309-18 : libvirt: Multiple vulnerabilities

high Nessus Plugin ID 70130

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'
