Updated tcpdump packages that correctly drop privileges on startup are now available.
Tcpdump is a command-line tool for monitoring network traffic. The Red Hat tcpdump packages advertise that by default tcpdump will drop permissions 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 are compiled so that by default tcpdump will drop privileges to the 'pcap' user.
