Descriptions

The phar_get_entry_data function in ext/phar/util.c in PHP before 5.5.30 and 5.6.x before 5.6.14 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a .phar file with a crafted TAR archive entry in which the Link indicator references a file that does not exist.

La función phar_get_entry_data en ext/phar/util.c en PHP en versiones anteriores a 5.5.30 y 5.6.x en versiones anteriores a 5.6.14 permite a atacantes remotos causar una denegación de servicio (referencia a puntero NULL y caída de aplicación) a través de un archivo .phar con una entrada de archivo TAR manipulada en la cual el indicador Link referencia a un archivo que no existe.

A flaw was found in the way the way PHP's Phar extension parsed Phar archives. A specially crafted archive could cause PHP to crash or, possibly, execute arbitrary code when opened.
