Upgrade Debian:8 wireshark to version 1.12.1+g01b65bf-4+deb8u16 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream wireshark package and not the wireshark package as distributed by Debian.
See How to fix? for Debian:8 relevant fixed versions and status.
In Wireshark 2.6.0, 2.4.0 to 2.4.6, and 2.2.0 to 2.2.14, the DNS dissector could crash. This was addressed in epan/dissectors/packet-dns.c by avoiding a NULL pointer dereference for an empty name in an SRV record.
