The Ubuntu security team deemed this advisory irrelevant for Ubuntu:18.10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream wireshark package and not the wireshark package as distributed by Ubuntu.
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.
