リモートWindowsホストにインストールされているWiresharkのバージョンは、2.0.11より前の2.0.x、または2.2.5より前の2.2.xです。このため、複数のサービス拒否脆弱性の影響を受けます。

  - 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. 認証されていないリモートの攻撃者がこの脆弱性を悪用し、パケットインジェクションや特別に細工されたキャプチャファイルを介して、CPUリソースを過剰に消費させ、サービス拒否状態を引き起こす可能性があります。
    (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. 認証されていないリモートの攻撃者がこの脆弱性を悪用し、パケットインジェクションや特別に細工されたキャプチャファイルを介して、サービス拒否状態を引き起こす可能性があります。
    (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)

Nessus はこれらの問題をテストしておらず、代わりにアプリケーションの自己報告されたバージョン番号にのみ依存しています。
