Descriptions

The read_request_line function in server/protocol.c in the Apache HTTP Server 2.4.12 does not initialize the protocol structure member, which allows remote attackers to cause a denial of service (NULL pointer dereference and process crash) by sending a request that lacks a method to an installation that enables the INCLUDES filter and has an ErrorDocument 400 directive specifying a local URI.

La función read_request_line en server/protocol.c del Servidor HTTP Apache en su versión 2.4.12 no inicializa el protocolo de estructura de miembro, lo que permite a atacantes remotos causar una denegación de servicio mediante la referencia a un puntero NULO y la caída procesos a través del envío de una solicitud que carece de un método para una instalación que habilita el filtro INCLUDE y tiene una directiva ErrorDocument 400 especificando un URI local.

A NULL pointer dereference flaw was found in the way httpd generated certain error responses. A remote attacker could possibly use this flaw to crash the httpd child process using a request that triggers a certain HTTP error.
