"The version of Wireshark installed on the remote macOS or Mac OS X
host is 2.0.x prior to 2.0.11 or 2.2.x prior to 2.2.5. It is,
therefore, affected by multiple denial of service vulnerabilities :

  - An infinite loop condition exists in the Netscaler file
    parser in the nstrace_read_v20() and nstrace_read_v30()
    functions within file wiretap/netscaler.c due to
    improper validation of certain input. An
    unauthenticated, remote attacker can exploit this, via a
    specially crafted capture file, to consume excessive
    memory resources, resulting in a denial of service
    condition. (CVE-2017-6467)

  - An out-of-bounds read error exists within various
    functions in file wiretap/netscaler.c when handling
    record lengths. An unauthenticated, remote attacker can
    exploit this, via a specially crafted capture file, to
    crash the Netscaler file parser process. (CVE-2017-6468)

  - A memory allocation issue exists in the
    dissect_ldss_transfer() function within file
    epan/dissectors/packet-ldss.c due to improper validation
    of certain input. An unauthenticated, remote attacker
    can exploit this, via packet injection or a specially
    crafted capture file, to crash the LDSS dissector
    process. (CVE-2017-6469)

  - An infinite loop condition exists in IAX2 in the
    iax2_add_ts_fields() function within file
    epan/dissectors/packet-iax2.c when processing
    timestamps. An unauthenticated, remote attacker can
    exploit this, via packet injection or a specially
    crafted capture file, to consume excessive CPU
    resources, resulting in a denial of service condition.
    (CVE-2017-6470)

  - An infinite loop condition exists in WSP in the
    dissect_wsp_common() function within file
    epan/dissectors/packet-wsp.c when handling capability
    lengths. An unauthenticated, remote attacker can exploit
    this, via packet injection or a specially crafted
    capture file, to cause a denial of service condition.
    (CVE-2017-6471)

  - An infinite loop condition exists in the RTMPT dissector
    in the dissect_rtmpt_common() function within file
    epan/dissectors/packet-rtmpt.c due to improper
    validation of certain input. An unauthenticated, remote
    attacker can exploit this, via packet injection or a
    specially crafted capture file, to consume excessive
    memory resources, resulting in a denial of service
    condition. (CVE-2017-6472)

  - A denial of service vulnerability exists in the
    process_packet_data() function within file wiretap/k12.c
    due to improper validation of certain input. An
    unauthenticated, remote attacker can exploit this, via a
    specially crafted capture file, to crash the K12 file
    parser process. (CVE-2017-6473)

  - An infinite loop condition exists in the NetScaler file
    parser in the nstrace_read_v10(), nstrace_read_v20(),
    and nstrace_read_v30() functions within file
    wiretap/netscaler.c when handling record sizes. An
    unauthenticated, remote attacker can exploit this, via a
    specially crafted capture file, to consume excessive
    memory resources, resulting in a denial of service
    condition. (CVE-2017-6474)
