Subject: [USN-19-1] squid vulnerabilities

===========================================================
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.
