A Squid security update has been released for Ubuntu Linux

==========================================================
Ubuntu Security Notice USN-19-1 November 06, 2004
squid vulnerabilities
CAN-2004-0832, CAN-2004-0918
==========================================================

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 2.5.5-6ubuntu0.2. In general, a standard system upgrade is sufficient to effect the necessary changes.



Details follow:

Recently, two Denial of Service vulnerabilities have been discovered in squid, a WWW proxy cache. Insufficient input validation in the NTLM authentication handler allowed a remote attacker to crash the service by sending a specially crafted NTLMSSP packet. Likewise, due to an insufficient validation of ASN.1 headers, a remote attacker could restart the server (causing all open connections to be dropped) by sending certain SNMP packets with negative length fields.
