xserver doesn't stop all connections to localhost
X.Org Bugzilla #23329: http://bugs.freedesktop.org/show_bug.cgi?id=23329
Patch #28648: http://bugs.freedesktop.org/attachment.cgi?id=28648
I noticed in xserver at os/access.c that xorg tries to stop connections
to localhost by checking against the address 127.0.0.1. However, RFC
3330 defines the localhost network as 127.0.0.0/8. This means that any
IPv4 address that starts with 127 is just another name for localhos
