Remote attackers could execute arbitrary commands as root by assigning specially crafted hostnames to X11 clients via XDMCP (CVE-2011-0465).

X11 6.6.2_x86: xrdb patch.
Date this patch was last updated by Sun : Jun/14/11

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.

The remote host is affected by the vulnerability described in GLSA-201412-09 (Multiple packages, Multiple vulnerabilities fixed in 2011)
