CVE-2019-8376 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:16.04.
NVD Description
Note: Versions mentioned in the description apply only to the upstream tcpreplay package and not the tcpreplay package as distributed by Ubuntu.
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.
