Descriptions

The mod_deflate module in Apache httpd 2.2.11 and earlier compresses large files until completion even after the associated network connection is closed, which allows remote attackers to cause a denial of service (CPU consumption).

El módulo mod_deflate en Apache httpd v2.2.11 y anteriores comprime archivos de gran tamaño hasta finalizar incluso después de que la conexión de red asociada está cerrada, lo cual permite a atacantes remotos provocar una denegación de servicio (consumo de CPU).
