Red Hat Product Errata RHSA-2013:1272 0 normal SHIPPED_LIVE Important: libvirt security and bug fix update 2013-09-19 22:02:43 UTC

Description Petr Matousek 2013-09-10 07:16:49 UTC 
The 'stats' variable in remoteDispatchDomainMemoryStats function was not initialized to NULL, so if some early validation of the RPC call fails, it is possible to jump to the 'cleanup' label and VIR_FREE an uninitialized pointer.

A remote user able to issue commands to libvirt daemon could use this flaw to crash libvirtd.
