Description Dhananjay Arunesh 2019-02-18 10:55:45 UTC
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.
