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

  - XPDF v4.04 was discovered to contain a stack overflow vulnerability via the Object::Copy class of
    object.cc files. (CVE-2022-33108)

  - There is an invalid memory access in the TextLine class in TextOutputDev.cc in Xpdf 4.0.4 because the text
    extractor mishandles characters at large y coordinates. It can be triggered by (for example) sending a
    crafted pdf file to the pdftotext binary, which allows a remote attacker to cause a Denial of Service
    (Segmentation fault) or possibly have unspecified other impact. (CVE-2022-30524)

  - xpdf 4.04 allocates excessive memory when presented with crafted input. This can be triggered by (for
    example) sending a crafted PDF document to the pdftoppm binary. It is most easily reproduced with the
    DCMAKE_CXX_COMPILER=afl-clang-fast++ option. (CVE-2022-30775)

  - XPDF v4.0.4 was discovered to contain a segmentation violation via the component /xpdf/AcroForm.cc:538.
    (CVE-2022-36561)

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。

  - xpdf 4.04 在呈現特製輸入時配置了過多的記憶體。(舉例來說) 將特製的 PDF 文件傳送至 pdftoppm 二進位檔即可觸發此問題。使用 DCMAKE_CXX_COMPILER=afl-clang-fast++ 選項最容易重現此問題。 (CVE-2022-30775)

請注意，Nessus 的判定取決於廠商所報告的套件是否存在。

遠端主機受到 GLSA-202409-25 中所述的弱點影響 (Xpdf：多個弱點)

    在 Xpdf 中發現多個弱點。如需詳細資訊，請檢閱下方提及的 CVE 識別碼。

Tenable 已直接從 Gentoo Linux 安全公告擷取前置描述區塊。

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

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。

  - xpdf 4.04 在提供构建的输入时分配过多内存。例如，这可通过将构建的 PDF 文档发送到 pdftoppm 二进制文件来触发。使用 DCMAKE_CXX_COMPILER=afl-clang-fast++ 选项可以轻松重现它。 (CVE-2022-30775)

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。

远程主机受到 GLSA-202409-25 中所述漏洞的影响（Xpdf：多个漏洞）

    已在 Xpdf 中发现多种漏洞。请检查下方引用的 CVE 标识符以了解详细信息。

Tenable 已直接从 Gentoo Linux 安全公告中提取上述描述块。

请注意，Nessus 尚未测试这些问题，而是只依据应用程序自我报告的版本号进行判断。

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。

  - xpdf 4.04 細工された入力が提示されたとき、過剰なメモリを割り当てます。これは、たとえば細工された PDF ドキュメントを pdftoppm バイナリに送信するなどすることで発生する可能性があります。これは、DCMAKE_CXX_COMPILER=afl-clang-fast++ オプションで最も簡単に複製できます。CVE-2022-30775

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.

  - xpdf 4.04 allocates excessive memory when presented with crafted input. This can be triggered by (for     example) sending a crafted PDF document to the pdftoppm binary. It is most easily reproduced with the     DCMAKE_CXX_COMPILER=afl-clang-fast++ option. (CVE-2022-30775)

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

The remote host is affected by the vulnerability described in GLSA-202409-25 (Xpdf: Multiple Vulnerabilities)

    Multiple vulnerabilities have been discovered in Xpdf. Please review the CVE identifiers referenced below     for details.

Tenable has extracted the preceding description block directly from the Gentoo Linux security advisory.

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