3. Problem description:

Squid is a full-featured Web proxy cache.

iDEFENSE reported a flaw in the squid SNMP module.  This flaw could allow
an attacker who has the ability to send arbitrary packets to the SNMP port
to restart the server, causing it to drop all open connections.  The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2004-0918 to this issue.

All users of squid should update to this erratum package, which contains a
backport of the security fix for this vulnerability.
