fwsnort invalid hex char



Hello debianers!

I run fwsnort to update and improve on my iptables rule sets. On
updating it's rules though I got this error message:

# iptables-restore < /path/to/fwsnort.save
iptables-restore v1.4.14: Invalid hex char '|' Error occurred at line:
4013 Try `iptables-restore -h' or 'iptables-restore --help' for more
information.

The line mentioned on the error contains the rule bellow:

-A FWSNORT_OUTPUT_ESTAB -p tcp -m tcp -m string --string "PRIVMSG "
--algo bm -m string --hex-string "|2d2d2d2d2d2d2d2d2d2d2d2d||2d||2d||

"[3006] SID2017291 ESTAB "

Upon removing this line, iptables-restore did it's job without
complaining. Since this line was automagically generated by "fwsnort
--update-rules ; fwsnort --ipt-sync",  I wonder if it's worth a bug
report.
