Description Petr Matousek 2014-01-14 08:51:07 EST
A race condition was found in the way libvirtd handled keepalive initialization requests when the connection is closed prior to establishing connection credentials.

An attacker able to establish a read-only connection to libvirtd could use this flaw to crash libvirtd, resulting in a denial of service.
