Description

Versions of Xorg 6.9.0 and greater have a bug in xf86Init.c, which allows non-root users to use the -modulepath, -logfile and -configure options. This allows loading of arbitrary modules which will execute as the root user, as well as a local DoS by overwriting system files.

Updated packages have been patched to correct these issues.
