Red Hat Product Errata RHSA-2004:478 0 normal SHIPPED_LIVE Moderate: XFree86 security update 2004-10-04 04:00:00 UTC

Description Mark J. Cox 2004-06-01 11:20:31 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 Red Hat Enterprise Linux 3 which
contained a backported patch that contains the flaw.

        CAN-2004-0419 Affects: 3AS 3WS 3ES 3Desktop

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

Comment 1 Mike A. Harris 2004-09-15 07:58:13 UTC
Is there a patch for this?

Comment 2 Mark J. Cox 2004-09-15 08:08:39 UTC
There is a patch at the URL in this bug entry.
