CVE-2013-6436 (GCVE-0-2013-6436)

Vulnerability from cvelistv5 – Published: 2014-01-07 19:00 – Updated: 2024-08-06 17:39
VLAI
Summary
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.
