遠端 Oracle Linux 7 主機中安裝的套件受到 ELSA-2019-2022 公告中提及的多個弱點影響。

  - 在 Poppler 0.68.0 中，Parser.cc 中的 Parser: : getObj() 函式可能會透過特製檔案造成無限遞迴。遠端攻擊者可利用這一點來發動 DoS 攻擊。(CVE-2018-16646)

  - 在 Poppler 0.71.0 中發現了一個問題 。GfxState.cc 中的 GfxColorSpace: : setDisplayProfile 存在記憶體洩漏問題，如 pdftocairo 所示。(CVE-2018-18897)

  - XRef.cc 中的 XRef: : getEntry 函式 (Poppler 0.72.0 版中) 未正確處理未配置的 Xref 項目，遠端攻擊者由此可透過特製的 PDF 文件造成拒絕服務 (NULL 指標解除參照)，前提是從 Parser.cc 中的 Parser: : makeStream 呼叫 XRef.h 中的 XRefEntry: : setFlag。(CVE-2018-20481)

  - 在 Poppler 0.72.0 中，因缺少對 dict 資料類型的檢查，可連線的 Object::dictLookup 宣告允許攻擊者造成拒絕服務，在 pdfdetach 中使用 FileSpec 類別 (在 FileSpec.cc 中) 即為一例。(CVE-2018-20650)

  - 在 Poppler 0.72.0 中，PDFDoc.cc 中的 PDFDoc: : setup 允許攻擊者透過特製的 PDF 檔案造成拒絕服務 (因為來自 PDFDoc: : setup 的傳回值錯誤，Object.h SIGABRT 會造成應用程式損毀)，這是因為在處理 extractPDFSubtype 期間，程式會錯誤處理 xref 資料結構。(CVE-2018-20662)

  - 在 Poppler 0.73.0 中，堆積型緩衝區過度讀取 (因 XRef.cc 中的 XRef:: : getEntry 函式有整數符號性錯誤) 弱點允許遠端攻擊者透過特製的 PDF 文件造成拒絕服務 (應用程式損毀)，甚至可能造成其他不明影響，pdftocairo 即為一例。(CVE-2019-7310)

  - 在 Poppler 0.74.0 中，位在 Stream.cc 的 ImageStream::getLine() 存在堆積型緩衝區向下寫入問題，攻擊者可透過將特製的 PDF 文件傳送至 pdfimages 二進位檔來觸發此問題 (舉例而言)，進而可造成拒絕服務 (區段錯誤)，或可能造成其他不明影響。
    (CVE-2019-9200)

  - 在 Poppler 0.74.0 中，CairoRescaleBox.cc downsample_row_box_filter 函式有堆積型緩衝區過度讀取情形。(CVE-2019-9631)

  - 在 Poppler 0.71.0 中發現了一個問題 。Object.h 中存在可連線的中止情形，此問題可導致拒絕服務，這是因為 FileSpec.cc 中的 EmbFile: : save2 在儲存內嵌檔案之前 缺少串流檢查。
    (CVE-2018-19058)

  - 在 Poppler 0.71.0 中發現了一個問題 。FileSpec.cc 中的 EmbFile: : save2 有超出邊界讀取情形，這會導致拒絕服務，utils/pdfdetach.cc 未在嘗試儲存前先驗證內嵌檔案即為一例。(CVE-2018-19059)

  - 在 Poppler 0.71.0 中發現了一個問題 。goo/GooString.h 有 NULL 指標解除參照情形，會導致拒絕服務，utils/pdfdetach.cc 未在建構儲存路徑前先驗證內嵌檔案的檔名即為一例。(CVE-2018-19060)

  - 在 Poppler 0.70.0 之前版本中，從 poppler_annot_file_attachment_get_attachment 呼叫 _poppler_attachment_new 時，程式會發生 NULL 指標解除參照。(CVE-2018-19149)

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。

(CVE-2019-9959)

  - A flaw was found in Poppler in the way certain PDF files were converted into HTML. A remote attacker could     exploit this flaw by providing a malicious PDF file that, when processed by the 'pdftohtml' program, would     crash the application causing a denial of service. (CVE-2020-27778)
