Bug Fix Advisory xorg-x11-server bug fix update

Advisory: RHBA-2010:0722-2
Type: Bug Fix Advisory
Severity: N/A
Issued on: 2010-09-29
Last updated on: 2010-09-29
Affected Products: RHEL Desktop Workstation (v. 5 client)
Red Hat Enterprise Linux (v. 5 server)
Red Hat Enterprise Linux Desktop (v. 5 client)

Details

Updated xorg-x11-server packages that resolve an issue are now available.

X.org X11 is an open source implementation of the X Window System. It provides
the basic low level functionality upon which full fledged graphical user
interfaces such as GNOME and KDE are designed.

These updated xorg-x11-server packages fix the following bug:

* the 'miDbePositionWindow' function allocates two pixmaps: a front buffer, and
a back buffer. If the buffers are supposed to be initialized, it validates a
graphic context (GC) against the front buffer, then uses it to fill and/or copy
both the front buffer and the back buffer, without revalidating. If the
acceleration architecture needed different GC functions for the two pixmaps, for
example if allocation of the front buffer exhausted video memory, then this
caused crashes because the GC was not validated for the back buffer pixmap. With
this update, the crashes no longer occur and GC validation works as expected.
(BZ#626328)

All users of xorg-x11-server are advised to upgrade to these updated packages,
which resolve this issue.
