How to fix?

Upgrade Debian:12 wireshark to version 1.10.1-1 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 Debian. See How to fix? for Debian:12 relevant fixed versions and status.

The dissect_dvbci_tpdu_hdr function in epan/dissectors/packet-dvbci.c in the DVB-CI dissector in Wireshark 1.8.x before 1.8.9 and 1.10.x before 1.10.1 does not validate a certain length value before decrementing it, which allows remote attackers to cause a denial of service (assertion failure and application exit) via a crafted packet.
