Description Petr Matousek 2013-07-19 16:01:37 UTC
A part of the returned monitor response was freed twice and caused crashes of the daemon when using guest agent cpu count retrieval.

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.
