Description |
|
|
Se ha descubierto un bug de formato en las versiones anteriores a la 2.8.19 del módulo mod_SSL para Apache 1.3.31. La vulnerabilidad reside en la función ssl_log() y la forma en que maneja los nombres de hosts ("hostnames"). La explotación de esta vulnerabilidad podría permitir a un atacante remoto y no autenticado ejecutar código remotamente mediante el envío de una petición HTTPS que contenga un valor "hostname" especialmente diseñado. |
