CentOS Errata and Security Advisory CESA-2011:0433
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 flaw was found in the X.Org X server resource database utility, xrdb.
Certain variables were not properly sanitized during the launch of a user’s
graphical session, which could possibly allow a remote attacker to execute
arbitrary code with root privileges, if they were able to make the display
manager execute xrdb with a specially-crafted X client hostname. For
example, by configuring the hostname on the target system via a crafted
DHCP reply, or by using the X Display Manager Control Protocol (XDMCP) to
connect to that system from a host that has a special DNS name.
(CVE-2011-0465)
Red Hat would like to thank Matthieu Herrb for reporting this issue.
Upstream acknowledges Sebastian Krahmer of the SuSE Security Team as the
original reporter.
Users of xorg-x11-server-utils should upgrade to this updated package,
which contains a backported patch to resolve this issue. All running X.Org
server instances must be restarted for this update to take effect.
