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:3.20 relevant fixed versions and status.

In Wireshark 2.4.0 to 2.4.5 and 2.2.0 to 2.2.13, the VLAN dissector could crash. This was addressed in epan/dissectors/packet-vlan.c by limiting VLAN tag nesting to restrict the recursion depth.
