Note: Versions mentioned in the description apply only to the upstream wireshark package and not the wireshark package as distributed by Ubuntu. See How to fix? for Ubuntu:14.04 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 Q.931 dissector could crash. This was addressed in epan/dissectors/packet-q931.c by avoiding a use-after-free after a malformed packet prevented certain cleanup.
