CVE-2013-4371 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.40% chance of exploitation in the next 30 days.
