Subject: [USN-414-1] Squid vulnerabilities

=========================================================== 
Ubuntu Security Notice USN-414-1           January 24, 2007
squid vulnerabilities
CVE-2007-0247, CVE-2007-0248
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 6.06 LTS
Ubuntu 6.10

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 6.06 LTS:
  squid                                    2.5.12-4ubuntu2.2

Ubuntu 6.10:
  squid                                    2.6.1-3ubuntu1.2

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

Details follow:

David Duncan Ross Palmer and Henrik Nordstrom discovered that squid 
incorrectly handled special characters in FTP URLs.  Remote users with 
access to squid could crash the server leading to a denial of service. 
(CVE-2007-0247)

Erick Dantas Rotole and Henrik Nordstrom discovered that squid could end 
up in an endless loop when exhausted of available external ACL helpers.  
Remote users with access to squid could cause CPU starvation, possibly 
leading to a denial of service.  This does not affect a default Ubuntu 
installation, since external ACL helpers must be configured and used.
(CVE-2007-0248)
