Hi Balint,
looking at
https://security-tracker.debian.org/tracker/source-package/wireshark
we have some CVEs open in Wheezy. Since Jessie ships the same version I
wanted to check that you're not already working (or planning to work) on
an update to avoid duplicate work. If not I'd start looking into this
for Wheezy/Jessie.
Cheers,
-- Guido
