Descriptions
The make_clickable function in wp-includes/formatting.php in WordPress before 3.1.1 does not properly check URLs before passing them to the PCRE library, which allows remote attackers to cause a denial of service (crash) via a comment with a crafted URL that triggers many recursive calls.
La función make_clickable en wp-includes/formatting.php en WordPress antes de v3.1.1 no comprueba las URL correctamente antes de pasarlas a la biblioteca PCRE, lo que permite a atacantes remotos provocar una denegación de servicio (caída) a través de un comentario con una URL modificada que lanza muchas llamadas recursivas.
