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

  - In the GD Graphics Library (aka LibGD) through 2.2.5, there is a heap-based buffer over-read in tiffWriter
    in gd_tiff.c. NOTE: the vendor says "In my opinion this issue should not have a CVE, since the GD and GD2
    formats are documented to be 'obsolete, and should only be used for development and testing purposes.'
    (CVE-2017-6363)

  - read_header_tga in gd_tga.c in the GD Graphics Library (aka LibGD) through 2.3.2 allows remote attackers
    to cause a denial of service (out-of-bounds read) via a crafted TGA file. (CVE-2021-38115)

  - gdImageGd2Ptr in gd_gd2.c in the GD Graphics Library (aka LibGD) through 2.3.2 has a double free. NOTE:
    the vendor's position is "The GD2 image format is a proprietary image format of libgd. It has to be
    regarded as being obsolete, and should only be used for development and testing purposes. (CVE-2021-40145)

    in gd_tiff.c. NOTE: the vendor says "In my opinion this issue should not have a CVE, since the GD and GD2

    (CVE-2017-6363)

  - gdImageClone in gd.c in libgd 2.1.0-rc2 through 2.2.5 has a NULL pointer dereference allowing attackers to
    crash an application via a specific function call sequence. Only affects PHP when linked with an external
    libgd (not bundled). (CVE-2018-14553)

  - When using the gdImageCreateFromXbm() function in the GD Graphics Library (aka LibGD) 2.2.5, as used in
    the PHP GD extension in PHP versions 7.1.x below 7.1.30, 7.2.x below 7.2.19 and 7.3.x below 7.3.6, it is
    possible to supply data that will cause the function to use the value of uninitialized variable. This may
    lead to disclosing contents of the stack that has been left there by previous code. (CVE-2019-11038)

遠端 Ubuntu 16.04 LTS/18.04 LTS/20.04 LTS/21.04 主機上安裝的套件受到 USN-5068-1 公告中所提及的多個弱點影響。

  - ** 有爭議** 在 2.2.5 版及更早版本的 GD 圖庫 (亦稱 LibGD) 中，gd_tiff.c 的 tiffWriter 中存在過度讀取堆積型緩衝區的情形。注意：供應商表示，我認為此問題不應有 CVE，因為 GD 和 GD2 格式已記錄為「過時，且應當只用於開發和測試用途」。(CVE-2017-6363)

  - 在 2.3.2 版及更早版本的 GD 圖庫 (亦稱 LibGD) 中，gd_gif_out.c 的 read_header_tga 允許遠端攻擊者透過特製 TGA 檔案，造成拒絕服務 (超出邊界讀取)。(CVE-2021-38115)

  - ** 有爭議 ** 在 2.3.2 版及更早版本的 GD 圖庫 (亦稱 LibGD) 中，gd_gd2.c 的 gdImageGd2Ptr 存在雙重釋放問題。注意：供應商的位置是 GD2 影像格式是 libgd 的專屬影像格式。必須將其視為「過時，且應當只用於開發和測試用途」。
    (CVE-2021-40145)

請注意，Nessus 並未測試此問題，而是僅依據應用程式自我報告的版本號碼作出判斷。

远程 Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 21.04 主机上安装的程序包受到 USN-5068-1 公告中提及的多个漏洞的影响。

  - **存在争议** 在 GD 图形库（亦称 LibGD）2.2.5 及之前版本中，gd_tiff.c 的 tiffWriter 中存在基于堆的缓冲区过度读取。注意：供应商表示，在他看来此问题不应具有 CVE，因为 GD 和 GD2 格式已记录为“过时，仅可用于开发和测试目的。”(CVE-2017-6363)

  - 在 GD 图形库（亦称 LibGD）2.3.2 及之前版本中，gd_tga.c 中的 read_header_tga 可让远程攻击者通过特制的 TGA 文件造成拒绝服务（越界读取）。(CVE-2021-38115)

  - **存在争议** 在 GD 图形库（亦即 LibGD）2.3.2 及之前版本中，gd_gd2.c 中的 gdImageGd2Ptr 存在双重释放。注意：供应商认为 GD2 图像格式是 libgd 的专有图像格式。该格式须被视为过时，且仅应用于开发和测试目的。

リモートのUbuntu 16.04 LTS/18.04 LTS/20.04 LTS/21.04ホストには、USN-5068-1のアドバイザリに記載された複数の脆弱性の影響を受けるパッケージがインストールされています。

  - **異論あり**2.2.5までのGDグラフィックライブラリ（別名LibGD）において、gd_tiff.cのtiffWriterでヒープベースのバッファオーバーリードがあります。注：ベンダーによると、個人的な見解として、GDおよびGD2フォーマットは「廃止され、開発とテストの目的でのみ使用する必要がある」として文書化されているため、この問題にはCVEを使用すべきではありません。（CVE-2017-6363）

  -2.3.2までのGDグラフィックライブラリ（別名LibGD）のgd_tga.cのread_header_tgaにより、リモート攻撃者が、細工されたTGAイメージを介して、サービス拒否（領域外読み取り）を引き起こす可能性があります。（CVE-2021-38115）

  - **異論あり**2.3.2までのGDグラフィックライブラリ（別名LibGD）のgd_gd2.cのgdImageGd2Ptrには、二重解放があります。注：ベンダーの立場は、GD2イメージフォーマットは、libgdの専用画像フォーマットであるというものです。これは古いものと見なさており、開発とテストの目的にのみ使用する必要があります。

Nessusはこ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。
