3. Description:
X.Org is an open source implementation of the X Window System. It provides
the basic low-level functionality that full-fledged graphical user
interfaces are designed upon.
A buffer over-read flaw was found in the way the X.Org server handled
XkbGetGeometry requests. A malicious, authorized client could use this flaw
to disclose portions of the X.Org server memory, or cause the X.Org server
to crash using a specially crafted XkbGetGeometry request. (CVE-2015-0255)
This issue was discovered by Olivier Fourdan of Red Hat.
All xorg-x11-server users are advised to upgrade to these updated packages,
which contain a backported patch to correct this issue.
4. Solution:
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
