CVE-2012-0064

First published: Thu Jan 19 2012(Updated: )

It was found that XKB actions for debugging X.org clients were enabled by default. This could cause a screen locking application such as gnome-screensaver to be killed when those key combinations were triggered. The debugging key actions were introduced in the following commit: <a href="http://cgit.freedesktop.org/xorg/xserver/commit/?id=7d2543a3cb3089241982ce4f8984fd723d5312a1">http://cgit.freedesktop.org/xorg/xserver/commit/?id=7d2543a3cb3089241982ce4f8984fd723d5312a1</a> Reference: <a href="http://thread.gmane.org/gmane.comp.security.oss.general/6725">http://thread.gmane.org/gmane.comp.security.oss.general/6725</a> Mitigation: <a href="http://thread.gmane.org/gmane.comp.security.oss.general/6725/focus=6731">http://thread.gmane.org/gmane.comp.security.oss.general/6725/focus=6731</a>
