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:10 relevant fixed versions and status.

In Wireshark 3.0.0 to 3.0.3 and 2.6.0 to 2.6.10, the Gryphon dissector could go into an infinite loop. This was addressed in plugins/epan/gryphon/packet-gryphon.c by checking for a message length of zero.
