Chad Loder has discovered vulnerabilities in tcpdump's ISAKMP protocol handler. During an audit to repair these issues, Bill Fenner discovered some related problems.

These vulnerabilities may be used by an attacker to crash a running `tcpdump' process. They can only be triggered if the `-v' command line option is being used.

NOTE: the racoon ISAKMP/IKE daemon incorporates the ISAKMP protocol handler from tcpdump, and so is also affected by this issue.
