Scientific Linux Security Update : xorg-x11-server on SL5.x, SL6.x i386/x86_64 (20131015)

medium Nessus Plugin ID 70468

Language:

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

A use-after-free flaw was found in the way the X.Org server handled ImageText requests. A malicious, authorized client could use this flaw to crash the X.Org server or, potentially, execute arbitrary code with root privileges. (CVE-2013-4396)

Users of proprietary drivers may need to reinstall the driver after applying this update. Some users have reported the inability to load X without reloading the nVidia or the ATI drivers. You can use 'yum reinstall' to easily reload drivers packaged in RPM format. RPMs for many common drivers can be found at the ELRepo Project. You can easily add the ELRepo Project's repository to your system with 'yum install yum-conf-elrepo' on SL 6 systems. Any issues with ELRepo packages should be directed to their mailing lists.

After installing the update, X must be restarted for the changes to take full effect.

Solution

Update the affected packages.
