Description Petr Matousek 2013-01-09 11:12:16 UTC

A flaw was found in the way message freeing on connection cleanup was handled under certain error conditions. A remote user able to issue commands to libvirt daemon could use this flaw to crash libvirtd or, potentially, escalate their privilages to that of libvirtd process.
