Descriptions

The dav_xml_get_cdata function in main/util.c in the mod_dav module in the Apache HTTP Server before 2.4.8 does not properly remove whitespace characters from CDATA sections, which allows remote attackers to cause a denial of service (daemon crash) via a crafted DAV WRITE request.

La función dav_xml_get_cdata en main/util.c en el módulo mod_dav en el Apache HTTP Server anterior a 2.4.8 no elimina debidamente caracteres de espacio en blanco de secciones CDATA, lo que permite a atacantes remotos causar una denegación de servicio (caída de demonio) a través de una solicitud DAV WRITE manipulada.
