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.
