Descriptions

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.

Vulnerabilidad de uso después de liberación en la función libxl_list_cpupool de la librería toolstack LibXL en Xen 4.2.x y 4.3.x, cuando se ejecuta "bajo presión de memoria", devuelve el puntero original cuando la función realloc falla, lo que permite a usuarios locales provocar una denegación de servicio (corrupción de heap y caída) y posiblemente ejecutar código arbitrario a través de vectores no especificados.

Multiple vulnerabilities have been found in Xen, the worst of which could lead to arbitrary code execution. Versions less than 4.3.2-r4 are affected.
