New xorg-server packages are available for Slackware 13.0, 13.1, 13.37, 14.0, 14.1, 14.2, and -current to fix security issues.

Here are the details from the Slackware 14.2 ChangeLog:
+--------------------------+
patches/packages/xorg-server-1.18.3-i586-3_slack14.2.txz: Rebuilt.
This update fixes two security issues:
A user authenticated to an X Session could crash or execute code in the
context of the X Server by exploiting a stack overflow in the endianness
conversion of X Events.
Uninitialized data in endianness conversion in the XEvent handling of the
X.Org X Server allowed authenticated malicious users to access potentially
privileged data from the X server.

(* Security fix *)
patches/packages/xorg-server-xephyr-1.18.3-i586-3_slack14.2.txz: Rebuilt.
