"Only  match  TCP packets with the SYN bit set and the ACK,RST and FIN
bits cleared"

Going by that description of --syn in iptables(8), I wouldn't expect --syn
to match SYN+FIN packets. I agree with comment in the netfilter-devel
mailing list thread (conveniently linked in the CVE, and predating the CVE)
that says you need an explicit --tcp-flags to match the FIN bit.

Did I miss something?
