xorg-server (2:1.11.3.901-1) unstable; urgency=low
* New upstream release candidate (1.11.4 RC1):
commit 663e92e660a15548f68a764479d7d59ed5c9af64
Author: Cyril Brulebois <k...@debian.org>
Date: Thu Jan 19 10:32:28 2012 +0100
Revert "XKB: Add debug key actions for grabs & window tree"
This reverts commit 7d2543a3cb3089241982ce4f8984fd723d5312a1.
Ctrl-Alt-Multiply would kill potentially any X screen locking program.
Revert the offending commit for now, fixing CVE-2012-0064.
