CVE-2013-6436 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:12.10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libvirt package and not the libvirt package as distributed by Ubuntu.
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.
