Gentoo Linux Security Advisory

Title: libvirt: Multiple vulnerabilities (GLSA 201309-18)
Severity: normal
Exploitable: remote
Date: September 25, 2013
Bug(s): #454588, #470096
ID: 201309-18

Synopsis

Multiple vulnerabilities have been found in libvirt, allowing
remote attackers to execute arbitrary code or cause Denial of Service.


Background

libvirt is a C toolkit for manipulating virtual machines.

Affected Packages

Package: app-emulation/libvirt
Vulnerable: < 1.0.5.1-r3
Unaffected: >= 1.0.5.1-r3
Architectures: All supported architectures


Description

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.

Resolution

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