This update for libvirt fixes one security issue :
CVE-2016-5008: Empty VNC password disables authentication. (bsc#987527) Additionally, the update includes the following non-security fixes :
Improve waiting for block job readines in virsh.
(bsc#989755)
Parse negative values in augeas lenses. (bsc#975729)
Restart daemons in %posttrans after connection drivers have been processed. (bsc#854343, bsc#968483)
Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
