Description Mark J. Cox 2004-06-01 11:18:56 UTC 
See URL; "Even when DisplayManager.requestPort is set to 0, xdm will
open a chooserFd tcp socket on all interfaces. This apparently cannot
be disabled by configuration and presents a possible security risk."  

Note that this issue does not affect upstream XFree86 4.3.0 but
affects the versions shipped with Fedora Core 1 and 2 which contained
a backported patch that contains the flaw.

        CAN-2004-0419 Affects: FC1 
        CAN-2004-0419 Affects: FC2 

This issue is minor severity as xdm is not used by default.
