CVE-2024-39884

Una regresión en el núcleo de Apache HTTP Server 2.4.60 ignora parte del uso de la configuración de controladores heredada basada en el tipo de contenido. "AddType" y configuraciones similares, en algunas circunstancias en las que los archivos se solicitan indirectamente, dan como resultado la divulgación del código fuente del contenido local. Por ejemplo, los scripts PHP pueden servirse en lugar de interpretarse. Se recomienda a los usuarios actualizar a la versión 2.4.61, que soluciona este problema.
