CVE-2018-9261 (opens in a new tab)How to fix?
Upgrade Debian:10 wireshark to version 2.4.6-1 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:10 relevant fixed versions and status.
In Wireshark 2.4.0 to 2.4.5 and 2.2.0 to 2.2.13, the NBAP dissector could crash with a large loop that ends with a heap-based buffer overflow. This was addressed in epan/dissectors/packet-nbap.c by prohibiting the self-linking of DCH-IDs.
