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:9 relevant fixed versions and status.

In Wireshark 2.6.0 to 2.6.3 and 2.4.0 to 2.4.9, the MS-WSP protocol dissector could crash. This was addressed in epan/dissectors/packet-mswsp.c by properly handling NULL return values.
