Descriptions

Buffer underflow in the PHP_FILTER_TRIM_DEFAULT macro in the filtering extension (ext/filter) in PHP 5.2.0 allows context-dependent attackers to execute arbitrary code by calling filter_var with certain modes such as FILTER_VALIDATE_INT, which causes filter to write a null byte in whitespace that precedes the buffer.

Desbordamiento de búfer en la macro HP_FILTER_TRIM_DEFAULT en el filtro de extensiones (ext/filter) del PHP 5.2.0 permite a atacantes dependientes del contexto ejecutar código de su elección llamando al filter_var con ciertos modos como el FILTER_VALIDATE_INT, lo que provoca que el filtro escriba un byte NULL en el espacio en blanco que precede al búfer.
