REDHAT-BUG-953107: Medium severity libvirt vulnerability
A denial of service flaw was found in the way storage pool manager of libvirt, a C toolkit to interact with the virtualization capabilities of recent versions of Linux (and other OSes), performed management of socket file descriptors when 'to list all volumes for the particular pool' request was issued (two socket file descriptors were leaked per "list all pool volumes" request). An uprivileged user could use this flaw to cause denial of service (make libvirtd daemon to exhaust / reach the maximum count of open file descriptors, the libvirtd daemon process was allowed to open, possibly preventing other users from use of libvirtd services till the libvirtd daemon was restarted).
