RHEL 2.1 : tcpdump (RHSA-2003:151)

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 that fix an infinite loop vulnerability and
drop privileges on startup are now available.

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

A vulnerability exists in tcpdump before 3.7.2 and is related to an
inability to handle unknown RADIUS attributes properly. This
vulnerability allows remote attackers to cause a denial of service
(infinite loop).

The Red Hat tcpdump packages advertise that, by default, tcpdump will
drop privileges to user 'pcap'. Due to a compilation error this did
not happen, and tcpdump would run as root unless the '-U' flag was
specified.

Users of tcpdump are advised to upgrade to these errata packages,
which contain a patch correcting the RADIUS issue and are compiled so
that by default tcpdump will drop privileges to the 'pcap' user.
