CVE-2013-6436

Priority
Medium
Description
The lxcDomainGetMemoryParameters method in lxc/lxc_driver.c in libvirt
1.0.5 through 1.2.0 does not properly check the status of LXC guests when
reading memory tunables, which allows local users to cause a denial of
service (NULL pointer dereference and libvirtd crash) via a guest in the
shutdown status, as demonstrated by the "virsh memtune" command.
