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.

Integer underflow in the visual_read function in wiretap/visual.c in Wireshark 1.2.x before 1.2.17 and 1.4.x before 1.4.7 allows remote attackers to cause a denial of service (application crash) via a malformed Visual Networks file that triggers a heap-based buffer over-read.
