NVD Description

Note: Versions mentioned in the description apply only to the upstream tcpreplay package and not the tcpreplay package as distributed by Alpine. See How to fix? for Alpine:3.24 relevant fixed versions and status.

An issue was discovered in Tcpreplay 4.3.1. A NULL pointer dereference occurred in the function get_layer4_v6() located at get.c. This can be triggered by sending a crafted pcap file to the tcpreplay-edit binary. It allows an attacker to cause a Denial of Service (Segmentation fault) or possibly have unspecified other impact.
