Subject: [USN-84-1] Squid vulnerabilities

===========================================================
Ubuntu Security Notice USN-84-1		  February 21, 2005
squid vulnerabilities
CAN-2005-0194, CAN-2005-0446
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)

The following packages are affected:

squid

The problem can be corrected by upgrading the affected package to
version 2.5.5-6ubuntu0.5.  In general, a standard system upgrade is
sufficient to effect the necessary changes.

Details follow:

When parsing the configuration file, squid interpreted empty Access
Control Lists (ACLs) without defined authentication schemes in a
non-obvious way. This could allow remote attackers to bypass intended
ACLs. (CAN-2005-0194)

A remote Denial of Service vulnerability was discovered in the domain
name resolution code. A faulty or malicious DNS server could stop the
Squid server immediately by sending a malformed IP address.
(CAN-2005-0446)
