Descriptions

pdo_sql_parser.re in the PDO extension in PHP before 5.3.14 and 5.4.x before 5.4.4 does not properly determine the end of the query string during parsing of prepared statements, which allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted parameter value.

pdo_sql_parser.re en la extensión PDO en PHP anteriores a v5.3.14 y v5.4.x anterior a v5.4.4 no determina de forma adecuada el final de la cadena en la petición durante un análisis sintáctico de estructuras preparadas, lo que permite a atacantes remotos a provocar una denegación de servicio (lectura fuera de los límites y caída de la aplicación)a través de un valor en el parámetro manipulado.
