Descriptions

Integer overflow in the phar_parse_tarfile function in tar.c in the phar extension in PHP before 5.3.14 and 5.4.x before 5.4.4 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted tar file that triggers a heap-based buffer overflow.

Desbordamiento de entero en la función phar_parse_tarfile en tar.c en la extensión en PHP v5.4.x anterior a v5.3.14 y v5.4.4 permite a atacantes remotos causar una denegación de servicio (caída de aplicación) o posiblemente ejecutar código arbitrario a través de un alquitrán diseñado archivo que provoca un desbordamiento de búfer basado en heap.
