Descriptions

Multiple integer overflows in PHP 4 before 4.4.8, and PHP 5 before 5.2.4, allow remote attackers to obtain sensitive information (memory contents) or cause a denial of service (thread crash) via a large len value to the (1) strspn or (2) strcspn function, which triggers an out-of-bounds read. NOTE: this affects different product versions than CVE-2007-3996.

Múltiples desbordamientos de entero en PHP 4 anterior a 4.4.8, y PHP 5 anterior a 5.2.4, permite a atacantes remotos obtener información sensible (contenido de memoria) o provocar denegación de servicio (caida de hilo) a través de un valor de len grande en la función (1) strspn o (2) strcspn, lo cual dispara un lectura fuera de límite.
