=========================================================== 
Ubuntu Security Notice USN-565-1           January 09, 2008

CVE-2007-6239
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 6.06 LTS
Ubuntu 6.10
Ubuntu 7.04

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

Ubuntu 6.06 LTS:
  squid                           2.5.12-4ubuntu2.3

Ubuntu 6.10:
  squid                           2.6.1-3ubuntu1.5

Ubuntu 7.04:
  squid                           2.6.5-4ubuntu2.1

Ubuntu 7.10:
  squid                           2.6.14-1ubuntu2.1

In general, a standard system upgrade is sufficient to effect the
necessary changes.
