Descriptions
The dechunk filter in PHP 5.3 through 5.3.2, when decoding an HTTP chunked encoding stream, allows context-dependent attackers to cause a denial of service (crash) and possibly trigger memory corruption via a negative chunk size, which bypasses a signed comparison, related to an integer overflow in the chunk size decoder.
El filtro dechunk en PHP 5.3 hasta v.5.3.2, cuando se decodifica un cadena HTTP fragmentada, permite a atacantes depediendo del contexto provocar una denegación de servicio (caída) y posiblemente una corrupción de memoria mediante un tamaño de fragmento negativo, lo que evita la comparación de signo, relativo a un desbordamiento de entero en el decodificados de tamaño del fragmento.
