Descriptions

The session extension in PHP 4 before 4.4.5, and PHP 5 before 5.2.1, calculates the reference count for the session variables without considering the internal pointer from the session globals, which allows context-dependent attackers to execute arbitrary code via a crafted string in the session_register after unsetting HTTP_SESSION_VARS and _SESSION, which destroys the session data Hashtable.

La extensión session de PHP 4 anterior a 4.4.5, y PHP 5 anterior a 5.2.1, calcula la cuenta de referencia para las variables de sesión sin considerar el puntero interno global de sesión, lo cual permite a atacantes locales o remotos dependiendo del contexto ejecutar código de su elección mediante una cadena manipulada en session_register tras desasignar HTTP_SESSION_VARS y _SESSION, lo cual destruye la tabla asociativa (Hashtable) de datos de sesión.
