リモートのWindowsホストにインストールされているWiresharkのバージョンは、2.0.5より前の2.0.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。

  - パケットが不適切に処理されているため、CORBA IDL ディセクタにサービス拒否の脆弱性が存在します。認証されていないリモートの攻撃者がこれを悪用して、特別に細工されたパケットまたはパケットトレースファイルを通じて、アプリケーションをクラッシュさせる可能性があります。Note that this vulnerability only affects 64-bit versions of Windows. (CVE-2016-6503)

  - packet-packetbb.c の dissect_pbb_tlvblock() 関数にあるゼロ除算の欠陥により、サービス拒否の脆弱性が存在します。An unauthenticated, remote attacker can exploit this, via a specially crafted packet or packet trace file, to cause an application crash. (CVE-2016-6505)

  - packet_wsp.c の add_headers() 関数に欠陥が存在します。これは、ゼロのオフセットが wkh_content_disposition() 関数により返されたときに発生します。An unauthenticated, remote attacker can exploit this, via a specially crafted packet or packet trace file, to cause an infinite loop, resulting in a denial of service condition. (CVE-2016-6506)

  - packet-rlc.c の rlc_decode_li() 関数が使用する整数データタイプが不適切なため、サービス拒否の脆弱性が存在します。An unauthenticated, remote attacker can exploit this, via a specially crafted packet or packet trace file, to cause a long loop and excessive CPU resource consumption, resulting in a denial of service condition. (CVE-2016-6508)

  - packet-ldss.c の dissect_ldss_transfer() 関数でサービス拒否の脆弱性が存在します。これはすでに存在する対話を再度作成する際に発生します。An unauthenticated, remote attacker can exploit this, via a specially crafted packet or packet trace file, to cause an application crash. (CVE-2016-6509)

  - packet-rlc.c の rlc_decode_li() 関数に、ユーザー指定入力の不適切な検証に起因するオーバーフロー状態が存在します。認証されていないリモートの攻撃者がこれを悪用して、特別に細工されたパケットまたはパケットトレースファイルを通じて、スタックベースのバッファオーバーフローを発生させ、結果としてサービス拒否状態を引き起す可能性があります。
    (CVE-2016-6510)

  - パケットが不適切に処理されているため、proto.c の proto_tree_add_text_valist_internal() 関数にサービス拒否の脆弱性が存在します。認証されていないリモートの攻撃者がこれを悪用して、特別に細工されたパケットまたはパケットトレースファイルを通じて、無限ループと過剰な CPU リソース消費を発生させる可能性があります。
    (CVE-2016-6511)

  - パケットが不適切に処理されているため、MMSE、WAP、WBXML、WSP のディセクタに複数の欠陥が存在します。An unauthenticated, remote attacker can exploit these issues, via a specially crafted packet or packet trace file, to cause an infinite loop, resulting in a denial of service condition. (CVE-2016-6512)

  - パケットが不適切に処理されているため、packet-wbxml.c の parse_wbxml_tag_defined() 関数にサービス拒否の脆弱性が存在します。An unauthenticated, remote attacker can exploit this, via a specially crafted packet or packet trace file, to cause an application crash. (CVE-2016-6513)

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。

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - wireshark: free operation on an uninitialized memory address in wiretap/netmon.c (CVE-2018-6836)

  - The srtp_add_address function in epan/dissectors/packet-rtp.c in the RTP dissector in Wireshark 1.10.x     before 1.10.7 does not properly update SRTP conversation data, which allows remote attackers to cause a     denial of service (application crash) via a crafted packet. (CVE-2014-2907)

  - The dissect_frame function in epan/dissectors/packet-frame.c in the frame metadissector in Wireshark     1.10.x before 1.10.8 interprets a negative integer as a length value even though it was intended to     represent an error condition, which allows remote attackers to cause a denial of service (application     crash) via a crafted packet. (CVE-2014-4020)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The version of Wireshark installed on the remote Windows host is 2.0.x prior to 2.0.5. It is, therefore, affected by multiple denial of service vulnerabilities :

  - A denial of service vulnerability exists in the CORBA     IDL dissector due to improper handling of packets. An     unauthenticated, remote attacker can exploit this, via a     specially crafted packet or packet trace file, to cause     an application crash. Note that this vulnerability only     affects 64-bit versions of Windows. (CVE-2016-6503)

  - A denial of service vulnerability exists due to a     divide-by-zero flaw in the dissect_pbb_tlvblock()     function in packet-packetbb.c. An unauthenticated,     remote attacker can exploit this, via a specially     crafted packet or packet trace file, to cause an     application crash. (CVE-2016-6505)

  - A flaw exists in the add_headers() function in     packet_wsp.c that is triggered when an offset of zero is     returned by the wkh_content_disposition() function. An     unauthenticated, remote attacker can exploit this, via a     specially crafted packet or packet trace file, to cause     an infinite loop, resulting in a denial of service     condition. (CVE-2016-6506)

  - A denial of service vulnerability exists due to an     incorrect integer data type used in the rlc_decode_li()     function in packet-rlc.c. An unauthenticated, remote     attacker can exploit this, via a specially crafted     packet or packet trace file, to cause a long loop and     excessive CPU resource consumption, resulting in a     denial of service condition. (CVE-2016-6508)

  - A denial of service vulnerability exists in the     dissect_ldss_transfer() function in packet-ldss.c that     is triggered when recreating a conversation that already     exists. An unauthenticated, remote attacker can exploit     this, via a specially crafted packet or packet trace     file, to cause an application crash. (CVE-2016-6509)

  - An overflow condition exists in the rlc_decode_li()     function in packet-rlc.c due to improper validation of     user-supplied input. An unauthenticated, remote attacker     can exploit this, via a specially crafted packet or     packet trace file, to cause a stack-based buffer     overflow, resulting in a denial of service condition.
    (CVE-2016-6510)

  - A denial of service vulnerability exists in the     proto_tree_add_text_valist_internal() function in     proto.c due to improper handling of packets. An     unauthenticated, remote attacker can exploit this, via a     specially crafted packet or packet trace file, to cause     a long loop and excessive CPU resource consumption.
    (CVE-2016-6511)

  - Multiple flaws exist in the MMSE, WAP, WBXML, and WSP     dissectors due to improper handling of packets. An     unauthenticated, remote attacker can exploit these     issues, via a specially crafted packet or packet trace     file, to cause an infinite loop, resulting in a denial     of service condition. (CVE-2016-6512)

  - A denial of service vulnerability exists in the     parse_wbxml_tag_defined() function in packet-wbxml.c due     to improper handling of packets. An unauthenticated,     remote attacker can exploit this, via a specially     crafted packet or packet trace file, to cause an     application crash. (CVE-2016-6513)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
