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
    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)

    have unspecified other impact. (CVE-2019-8377)

  - An issue was discovered in Tcpreplay 4.3.1. An invalid memory access occurs in do_checksum in checksum.c.
