Oracle Linux 8：GNOME (ELSA-2021-1586)

high Nessus Plugin ID 149947

語系：

概要

遠端 Oracle Linux 主機缺少一個或多個安全性更新。

說明

遠端 Oracle Linux 8 主機中安裝的套件受到 ELSA-2021-1586 公告中提及的多個弱點影響。

- Webkit WebKitGTK 2.30.0 的 WebSocket 功能中有一個程式碼執行弱點。特製的網頁可觸發釋放後使用弱點，進而導致遠端程式碼執行。攻擊者可誘騙使用者造訪網頁以觸發此弱點。(CVE-2020-13543)

- WebKitGTK 瀏覽器 2.30.1 x64 版中有一個可遭惡意利用的釋放後使用弱點。特製的 HTML 網頁可造成釋放後使用情形，進而導致遠端程式碼執行。受害者必須造訪惡意網站才能觸發此弱點。(CVE-2020-13584)

- 在 GNOME GLib (即 glib2.0) 2.60.0 之前版本中，金鑰檔設定後端會建立使用 g_file_make_directory_with_parents (kfsb-> dir、NULL、NULL) 的目錄，以及使用 g_file_replace_contents (kfsb-> file、contents、length、NULL、FALSE、G_FILE_CREATE_REPLACE_DESTINATION、NULL、NULL、NULL) 的檔案。
因此，它不會正確限制目錄 (和檔案) 權限，而是會針對目錄使用 0777 權限，針對檔案使用預設檔案權限。此問題與 CVE-2019-12450 類似。(CVE-2019-13012)

- 已透過改善記憶體處理解決一個類型混淆問題。已在 Safari 14.0 中修正此問題。
處理惡意特製的網路內容可能會導致任意程式碼執行。(CVE-2020-9948)

- 已透過改進記憶體管理解決釋放後使用問題。已在 Safari 14.0 中修正此問題。
處理惡意特製的網路內容可能會導致任意程式碼執行。(CVE-2020-9951)

- 已透過改善邊界檢查修正超出邊界寫入問題。已在 Safari 14.0 中修正此問題。處理惡意建構的 Web 內容可能導致程式碼執行。(CVE-2020-9983)

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。
