FreeBSD : XFree86 opens a chooserFd TCP socket even when DisplayManager.requestPort is 0 (ff00f2ce-c54c-11d8-b708-00061bc2ad93)

Synopsis :

The remote FreeBSD host is missing a security-related update.

Description :

When the IPv6 code was added to xdm a critical test to disable xdmcp
was accidentally removed. This caused xdm to create the chooser socket
regardless if DisplayManager.requestPort was disabled in xdm-config or
not.
