I couldn't reproduce CVE-2015-3414 in wheezy and squeeze so I marked it as n/a
in the security-tracker. As for CVE-2015-3415, I'm not sure how one is supposed
to reproduce it in the first place, so I can't really tell right now.

I don't think squeeze is affected by CVE-2015-3416 at all (even valgrind shows
nothing), but I'll leave that to the LTS team to decide.

In general CVE-2015-3416 doesn't seem all that critical, but since it's been
fixed in jessie I don't see why it shouldn't be fixed in wheezy as well. But
first I'd like to understand if wheezy is affected by CVE-2015-3415 or not.

Thanks for your work.

Cheers
