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

The ISAKMP parser in tcpdump 3.6 through 3.7.1 allows remote attackers to cause a denial of service (CPU consumption) via a certain malformed ISAKMP packet to UDP port 500, which causes tcpdump to enter an infinite loop.

Users of tcpdump are advised to upgrade to these errata packages which contain a patch to correct this issue.
