I've had a look at this. I set up cacti on a wheezy VM, and I could reproduce
CVE-2016-3172. However, like you, I couldn't reproduce CVE-2016-3659. I don't
know if we are vulnerable or not, maybe we are and the attack needs some
changes. In any case, I think the fix is very safe, sanitizing parenthesis, so I
think we can just ship it. What do you think? Please see the attached debdiff.
Thanks,
Emilio
