NVD Description

Note: Versions mentioned in the description apply only to the upstream xen package and not the xen package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

Use-after-free vulnerability in the libxl_list_cpupool function in the libxl toolstack library in Xen 4.2.x and 4.3.x, when running "under memory pressure," returns the original pointer when the realloc function fails, which allows local users to cause a denial of service (heap corruption and crash) and possibly execute arbitrary code via unspecified vectors.
