=========================================================== 
Ubuntu Security Notice USN-364-1           October 16, 2006
xinit vulnerability
CVE-2006-5214
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 5.10
Ubuntu 6.06 LTS

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 5.10:
  xinit                                    1.0+0.99.1-4ubuntu0.1

Ubuntu 6.06 LTS:
  xinit                                    1.0.1-0ubuntu3.1

After a standard system upgrade you need to restart your session to
effect the necessary changes.

Details follow:

A race condition existed that would allow other local users to see error 
messages generated during another user's X session.  This could allow 
potentially sensitive information to be leaked.
