NVD Description

Note: Versions mentioned in the description apply only to the upstream wireshark package and not the wireshark package as distributed by Alpine. See How to fix? for Alpine:3.17 relevant fixed versions and status.

In Wireshark 2.2.0 to 2.2.6, the ROS dissector could crash with a NULL pointer dereference. This was addressed in epan/dissectors/asn1/ros/packet-ros-template.c by validating an OID.
