Desbordamiento de entero en la función wordwrap en string.c en PHP 4.4.2 y 5.1.2 podría permitir a atacantes dependientes del contexto ejecutar código arbitrario a través de ciertos argumentos largos que provoca la asignación de un búfer pequeño, lo que desencadena un desbordamiento de búfer basado en memoria dinámica en una llamada a la función memcpy, una vulnerabilidad diferente a CVE-2002-1396.
