How to fix?

Upgrade Alpine:3.17 wireshark to version 2.4.5-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 2.2.0 to 2.2.12 and 2.4.0 to 2.4.4, the pcapng file parser could crash. This was addressed in wiretap/pcapng.c by adding a block-size check for sysdig event blocks.
