Red Hat Product Errata RHSA-2014:0103 0 normal SHIPPED_LIVE Moderate: libvirt security and bug fix update 2014-01-28 22:49:13 UTC

Description Petr Matousek 2014-01-14 13:51:07 UTC 
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.
