I'm rather sure that FreeBSD is vulnerable to the tcpdump issue (since I don't see any reason we should not be), but unfortunately the proof-of-concept code does not work on FreeBSD, so I have not yet been able to verify the problem. That said, an advisory is upcomming, but I cannot give you a date yet. It should be noted that the tcpdump issue is DoS, not remote code execution. I do not know the status of the gzip issue, but I will look into it. Both tcpdump and gzip issues are certainly not ignored, but preparing an advisory (and all the related tasks) takes some time. --=20 Simon L.
