Fixed In Version: libvirt-0.10.2-18.el6_4.4
Doc Type: Bug Fix
Doc Text:
Due to a race condition in the libvirt client library, any application using libvirt could terminate unexpectedly with a segmentation fault. This happened when one thread executed the connection close callback, while another one freed the connection object, and the connection callback thread then accessed memory that had been already freed. This update fixes the possibility of freeing the callback data when they are still being accessed.
