CVE-2016-6312

Estado: ModificadaMedia (6.5)—

El componente mod_dontdothat del módulo de Apache mod_dav_svn en Subversion como empaquetado en Red Hat Enterprise Linux versión 5.11, no detecta apropiadamente la recursión durante la expansión de la entidad, lo que permite a los usuarios autenticados remotos con acceso al repositorio webdav causar una denegación del servicio (consumo de memoria y bloqueo de httpd) ). NOTA: Existe como una regresión de CVE-2009-1955.
