Descriptions

The sapi_header_op function in main/SAPI.c in PHP 5.4.0RC2 through 5.4.0 does not properly determine a pointer during checks for %0D sequences (aka carriage return characters), which allows remote attackers to bypass an HTTP response-splitting protection mechanism via a crafted URL, related to improper interaction between the PHP header function and certain browsers, as demonstrated by Internet Explorer and Google Chrome. NOTE: this vulnerability exists because of an incorrect fix for CVE-2011-1398.

La función sapi_header_op en main/SAPI.c en PHP v5.4.0 hasta v5.4.0RC2, no determina correctamente un puntero durante los controles secuencias %0D (también conocidos como caracteres de retorno de carro), lo que permite a atacantes remotos evitar un mecanismo de protección de HTTP response-splitting a través de una URL modificada, relacionada con la interacción inadecuada entre la función de cabecera de PHP y algunos navegadores, como se demuestra con Internet Explorer y Google Chrome. NOTA: esta vulnerabilidad se debe a una solución incorrecta para CVE-2011-1398.
