How to fix?

Upgrade Alpine:3.17 wireshark to version 2.6.2-r0 or higher.

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 2.6.0 to 2.6.1, 2.4.0 to 2.4.7, and 2.2.0 to 2.2.15, the ISMP dissector could crash. This was addressed in epan/dissectors/packet-ismp.c by validating the IPX address length to avoid a buffer over-read.
