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)

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。

請注意，Nessus 的判定取決於廠商所報告的套件是否存在。

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 の xpdf/Dict.cc にある 4.04関数Dict::find にスタックオーバーフローの脆弱性があり、ローカルの攻撃者はサービス拒否を引き起こすことができます。CVE-2022-45586

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 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.

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

  - Stack overflow vulnerability in function Dict::find in xpdf/Dict.cc in xpdf 4.04, allows local attackers     to cause a denial of service. (CVE-2022-45586)

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