Scientific Linux Security Update : xorg-x11 on SL4.x i386/x86_64

High Nessus Plugin ID 61015


The remote Scientific Linux host is missing one or more security updates.


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.


Update the affected packages.
