RHEL 3 : tcpdump (RHSA-2005:421)

medium Nessus Plugin ID 18239

Synopsis

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

Description

Updated tcpdump packages that fix several security issues are now available.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

These updated packages also add support for output files larger than 2 GB, add support for some new VLAN IDs, and fix message parsing on 64bit architectures.

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

Several denial of service bugs were found in the way tcpdump processes certain network packets. It is possible for an attacker to inject a carefully crafted packet onto the network, crashing a running tcpdump session. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2005-1278, CVE-2005-1279, and CVE-2005-1280 to these issues.

Additionally, the tcpdump utility can now write a file larger than 2 GB, parse some new VLAN IDs, and parse messages on 64bit architectures.

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

Solution

Update the affected libpcap and / or tcpdump packages.
