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.

CVE-2013-4371 [MEDIUM] CVE-2013-4371 xen: use-after-free in libxl_list_cpupool under memory pressure (XSA-70)
CVE-2013-4371 xen: use-after-free in libxl_list_cpupool under memory pressure (XSA-70)
If realloc(3) fails then libxl_list_cpupool will incorrectly return
the now-free original pointer.
An attacker may be able to cause a multithreaded toolstack using this
function to race against itself leading to heap corruption and a
potential DoS.
Depending on the malloc implementation code execution cannot be ruled
out.
