CWE-264  (opens in a new tab)

How to fix?

Upgrade libvirt to version 1.2.1 or higher.

Overview

Affected versions of this package are vulnerable to Access Restriction Bypass. The libxlDomainGetNumaParameters function in the libxl driver (libxl/libxl_driver.c) in libvirt before 1.2.1 does not properly initialize the nodemap, which allows local users to cause a denial of service (invalid free operation and crash) or possibly execute arbitrary code via an inactive domain to the virsh numatune command.
