Summary
Red Hat Security Advisory: tcpdump security update

Notes

Topic
Updated tcpdump packages that fix an infinite loop vulnerability and drop privileges on startup are now available.
Details
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.
