There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - FFmpeg before commit cced03dd667a5df6df8fd40d8de0bff477ee02e8 contains multiple out of array access
    vulnerabilities in the mms protocol that can result in attackers accessing out of bound data. This attack
    appear to be exploitable via network connectivity. This vulnerability appears to have been fixed in
    cced03dd667a5df6df8fd40d8de0bff477ee02e8 and later. (CVE-2018-1999010)

  - In FFmpeg 4.0.1, due to a missing check of a profile value before setting it, the
    ff_mpeg4_decode_picture_header function in libavcodec/mpeg4videodec.c may trigger a NULL pointer
    dereference while converting a crafted AVI file to MPEG4, leading to a denial of service. (CVE-2018-13301)

  - In FFmpeg 4.0.1, a missing check for failure of a call to init_get_bits8() in the avpriv_ac3_parse_header
    function in libavcodec/ac3_parser.c may trigger a NULL pointer dereference while converting a crafted AVI
    file to MPEG4, leading to a denial of service. (CVE-2018-13303)

  - In libavcodec in FFmpeg 4.0.1, improper maintenance of the consistency between the context profile field
    and studio_profile in libavcodec may trigger an assertion failure while converting a crafted AVI file to
    MPEG4, leading to a denial of service, related to error_resilience.c, h263dec.c, and mpeg4videodec.c.
    (CVE-2018-13304)

Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且廠商未提供可用的修補程式。

  - 在 FFmpeg 4.0.1中libavcodec/ac3_parser.c 的 avpriv_ac3_parse_header 函式中缺少對 init_get_bits8() 呼叫失敗的檢查可能會在將特製 AVI 檔案轉換為 MPEG4 時觸發 NULL 指標解除參照進而導致拒絕服務。 (CVE-2018-13303)

請注意，Nessus 的判定取決於廠商所報告的套件是否存在。

Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。

  - 在 4.0.1FFmpeg中libavcodec/ac3_parser.c 的 avpriv_ac3_parse_header 函数中缺少对调用 init_get_bits8() 失败的检查可能在将构建的 AVI 文件转换为 MPEG4 时触发空指针取消引用从而导致拒绝服务。 (CVE-2018-13303)

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。

Linux/Unix ホストには、ベンダーが提供するパッチが利用できない脆弱性の影響を受ける複数のパッケージがインストールされています。

  - FFmpeg 4.0.1において、libavcodec/ac3_parser.c の avpriv_ac3_parse_header 関数にある init_get_bits8() への呼び出しの失敗がチェックされないため、細工された AVI ファイルを MPEG4 へ変換する際に NULL ポインターデリファレンスを発生させ、サービス拒否を引き起こす可能性があります。CVE-2018-13303

Nessus は、ベンダーによって報告されたパッケージの存在に依存していることに注意してください。

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - In FFmpeg 4.0.1, a missing check for failure of a call to init_get_bits8() in the avpriv_ac3_parse_header     function in libavcodec/ac3_parser.c may trigger a NULL pointer dereference while converting a crafted AVI     file to MPEG4, leading to a denial of service. (CVE-2018-13303)

Note that Nessus relies on the presence of the package as reported by the vendor.
