    Description
    ===========
    
    - CVE-2019-8376 (denial of service)
    
    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-2019-8377 (denial of service)
    
    An issue was discovered in tcpreplay 4.3.1. A NULL pointer dereference
    occurred in the function get_ipv6_l4proto() 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-2019-8381 (arbitrary code execution)
    
    An issue was discovered in tcpreplay 4.3.1. An invalid memory access
    occurs in do_checksum in checksum.c. It 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.
    
    Impact
    ======
    
    A remote attacker is able to cause a denial of service, or execute
    arbitrary code, with a specially crafted pcap file.
