NVD Description

Note: Versions mentioned in the description apply only to the upstream wireshark package and not the wireshark package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

In Wireshark 2.2.0 to 2.2.4 and 2.0.0 to 2.0.10, there is an LDSS dissector crash, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-ldss.c by ensuring that memory is allocated for a certain data structure.
