Updated xorg-x11-server packages that fix one security issue and several bugs are now available for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having low security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links associated with each description below.
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.
Security Fix
- CVE-2013-1940
- A flaw was found in the way the X.org X11 server registered new hot plugged devices. If a local user switched to a different session and plugged in a new device, input from that device could become available in the previous session, possibly leading to information disclosure.
This issue was found by David Airlie and Peter Hutterer of Red Hat.
Bug Fixes
- BZ#915202
- A previous upstream patch modified the Xephyr X server to be resizeable, however, it did not enable the resize functionality by default. As a consequence, X sandboxes were not resizeable on Red Hat Enterprise Linux 6.4 and later. This update enables the resize functionality by default so that X sandboxes can now be resized as expected.
- BZ#957298
- In Red Hat Enterprise Linux 6, the X Security extension (XC-SECURITY) has been disabled and replaced by X Access Control Extension (XACE). However, XACE does not yet include functionality that was previously available in XC-SECURITY. With this update, XC-SECURITY is enabled in the xorg-x11-server spec file on Red Hat Enterprise Linux 6.
- BZ#969538
- Upstream code changes to extension initialization accidentally disabled the GLX extension in Xvfb (the X virtual frame buffer), rendering headless 3D applications not functional. An upstream patch to this problem has been backported so the GLX extension is enabled again, and applications relying on this extension work as expected.
All xorg-x11-server users are advised to upgrade to these updated packages, which contain backported patches to correct these issues.
