Description Vincent Danen 2013-10-03 14:21:18 EDT
A flaw was found in libvirt where libvirtd could crash due to how XML was parsed [1].  With the introduction of ACL permissions in libvirt 1.1.0, this flaw could be manipulated to allow a remote user with connect:read privileges to elevate them to the more permissive domain:write privilege.

This vulnerability was introduced in libvirt 1.1.0.

Comment 2 Vincent Danen 2013-10-03 14:23:48 EDT

Not vulnerable.

This issue did not affect the versions of libvirt package as shipped with Red Hat Enterprise Linux 5 and 6.
