Subject: [USN-67-1] Squid vulnerabilities

===========================================================
Ubuntu Security Notice USN-67-1		   January 20, 2005
squid vulnerabilities
CAN-2005-0094, CAN-2005-0095, CAN-2005-0096, CAN-2005-0097
===========================================================

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 2.5.5-6ubuntu0.3.  In general, a standard system upgrade is
sufficient to effect the necessary changes.

Details follow:

infamous41md discovered several Denial of Service vulnerabilities in
squid.

A malicious Gopher server could crash squid by sending a line bigger
than 4096 bytes. (CAN-2005-0094)

If squid is configured to send WCPP (Web Cache Communication Protocol)
messages to a "home router", an attacker who was able to send UDP
packets with a forged source address of this router could crash the

erver with a specially crafted WCPP message. (CAN-2005-0095)

Previous versions of squid have a memory leak which gradually cause
memory exhaustion and eventual termination. (CAN-2005-0096)

A remote attacker could crash the server by sending a specially
crafted NTLM type 3 packet. (CAN-2005-0097)
