"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."
