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

  <affected>
    <package name="app-emulation/libvirt" auto="yes" arch="*">
      <unaffected range="ge">1.0.5.1-r3</unaffected>
      <vulnerable range="lt">1.0.5.1-r3</vulnerable>
    </package>
  </affected>
  <background>
    <p>libvirt is a C toolkit for manipulating virtual machines.</p>
  </background>
  <description>
    <p>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.
    </p>
  </description>
  <impact type="normal">
    <p>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.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All libvirt users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose
      "&gt;=app-emulation/libvirt-1.0.5.1-r3"
    </code>
