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.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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. (CVE-2019-8376)

Note that Nessus relies on the presence of the package as reported by the vendor.

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - An issue was discovered in Tcpreplay 4.3.1. A NULL pointer dereference occurred in the function
