package/apache/0003-CVS-2017-9798.patch

   1 core: Disallow Methods' registration at run time (.htaccess), they may
   2 be used only if registered at init time (httpd.conf).
   3
   4 Calling ap_method_register() in children processes is not the right scope
   5 since it won't be shared for all requests.
