A crafted URI sent to httpd configured as a forward proxy (ProxyRequests
on) can cause a crash (NULL pointer dereference) or, for configurations
mixing forward and reverse proxy declarations, can allow for requests to be
directed to a declared Unix Domain Socket endpoint (Server Side Request
Forgery). This issue affects Apache HTTP Server 2.4.7 up to 2.4.51
(included).
