RHEL 2.1 : tcpdump (RHSA-2003:085)

This script is Copyright (C) 2004-2014 Tenable Network Security, Inc.


Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated tcpdump packages are available to fix a denial of service
vulnerability in tcpdump.

[Updated 12 March 2003] Added packages for Red Hat Enterprise Linux ES
and Red Hat Enterprise Linux WS

Tcpdump is a command-line tool for monitoring network traffic.

The ISAKMP parser in tcpdump 3.6 through 3.7.1 allows remote attackers
to cause a denial of service (CPU consumption) via a certain malformed
ISAKMP packet to UDP port 500, which causes tcpdump to enter an
infinite loop.

Users of tcpdump are advised to upgrade to these errata packages which
contain a patch to correct this issue.
