Subject: [USN-1107-1] x11-xserver-utils vulnerability

===========================================================
Ubuntu Security Notice USN-1107-1            April 06, 2011
x11-xserver-utils vulnerability
CVE-2011-0465
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 8.04 LTS
Ubuntu 9.10
Ubuntu 10.04 LTS
Ubuntu 10.10

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

The problem can be corrected by upgrading your system to the
following package versions:

Ubuntu 8.04 LTS:
  x11-xserver-utils               7.3+2ubuntu0.1

Ubuntu 9.10:
  x11-xserver-utils               7.4+2ubuntu3.1

Ubuntu 10.04 LTS:
  x11-xserver-utils               7.5+1ubuntu2.1

Ubuntu 10.10:
  x11-xserver-utils               7.5+2ubuntu1.1

After a standard system update you need to reboot your computer to make
all the necessary changes.

Details follow:

Sebastian Krahmer discovered that the xrdb utility incorrectly filtered
crafted hostnames. An attacker could use this flaw with a malicious
DHCP server or with a remote xdmcp login and execute arbitrary code,
resulting in root privilege escalation.
