Crafted ICMP Messages Can Cause Denial of Service - Cisco Systems

This script is (C) 2010-2014 Tenable Network Security, Inc.


Synopsis :

The remote device is missing a vendor-supplied security patch

Description :

A document that describes how the Internet Control Message Protocol
(ICMP) could be used to perform a number of Denial of Service (DoS)
attacks against the Transmission Control Protocol (TCP) has been made
publicly available. This document has been published through the
Internet Engineering Task Force (IETF) Internet Draft process, and is
entitled "ICMP Attacks Against TCP"
(draft-gont-tcpm-icmp-attacks-03.txt ).
These attacks, which only affect sessions terminating or originating on
a device itself, can be of three types:
Successful attacks may cause connection resets or reduction of
throughput in existing connections, depending on the attack type.
Multiple Cisco products are affected by the attacks described in this
Internet draft.
Cisco has made free software available to address these
vulnerabilities. In some cases there are workarounds available to
mitigate the effects of the vulnerability.
