Synopsis:	Moderate: xorg-x11-server-utils security update
Issue date:	2011-04-11
CVE Names:	CVE-2011-0465

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)

All running X.Org server instances must be restarted for this update to
take effect.
