An updated xorg-x11-server-utils package that fixes one bug is now available for Red Hat Enterprise Linux 6.
The xorg-x11-server-utils package contains a collection of utilities used to modify and query the runtime configuration of the X.Org server. X.Org is an open source implementation of the X Window System.
A previous advisory, the RHSA-2011:0433 xorg-x11-server-utils security update, applied a backported patch to fix a flaw in the X server resource database utility, xrdb. While this patch resolved the security issue, it also introduced an error in the macro expansion mechanism. Consequent to this, an attempt to run the xrdb utility could fail with the following messages written to standard error:
sh: -c: line 0: unexpected EOF while looking for matching `"'
sh: -c: line 1: syntax error: unexpected end of file
With this update, the underlying source code has been adapted to correct the macro expansion mechanism, and the xrdb utility now works as expected.
All users of xorg-x11-server-utils are advised to upgrade to this updated package, which fixes this bug. Note that all running instances of the X.Org server must be restarted for this update to take effect.
