RHSA-2003-151: arpwatch Vulnerability Scan

Vulnerability Scan Summary
Check for the version of the arpwatch packages

Detailed Explanation for this Vulnerability Test

Updated tcpdump packages that fix an infinite loop vulnerability and drop
rights 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
rights 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 rights to the 'pcap' user.
