Synopsis: Moderate: xorg-x11 security update
Issue Date: 2011-04-11
CVE Numbers: CVE-2011-0465
—
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.
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 should upgrade to these updated packages, which contain a
backported patch to resolve this issue. All running X.Org server instances
must be restarted for this update to take effect.
