RHSA-2004:219 - Security Advisory

Synopsis

tcpdump security update

Type/Severity

Security Advisory: Low

Topic

Updated tcpdump, libpcap, and arpwatch packages fix vulnerabilities in
ISAKMP parsing.

Description

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

Tcpdump v3.8.1 and earlier versions contained multiple flaws in the
packet display functions for the ISAKMP protocol. Upon receiving
specially crafted ISAKMP packets, TCPDUMP would try to read beyond
the end of the packet capture buffer and subsequently crash.

Users of tcpdump are advised to upgrade to these erratum packages, which
contain backported security patches and are not vulnerable to these issues.

Solution

Before applying this update, make sure all previously released errata

Please note that this update is available via Red Hat Network. To use Red
Hat Network, launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
