简介
远程 Oracle Linux 主机缺少一个或多个安全更新。描述
远程 Oracle Linux 8 主机上安装的程序包受到 ELSA-2020-1598 公告中提及的多个漏洞的影响。- LibreOffice 具有“隐藏模式”，在该模式中，只有被视为“可信”位置中的文档可以检索远程资源。此模式不是默认模式，但可由想要禁用 LibreOffice 在文档中包含远程资源的用户启用。存在一个缺陷，即项目符号被版本 6.2.5 之前的此项保护遗漏。此问题影响以下版本：6.2.5 之前的 Document Foundation LibreOffice 版本。(CVE-2019-9849)
- LibreOffice 通常与 LibreLogo 捆绑，后者是可编程的 turtle 向量图形脚本，可执行启动该脚本的文档中包含的任意 python 命令。LibreOffice 还有一项功能，即其中的文档可以指定可在各种文档脚本事件（例如 mouse-over 等）上执行的预安装脚本。已添加保护以解决 CVE-2019-9848，进而阻止通过脚本事件处理程序调用 LibreLogo。然而，LibreOffice 中的 url 验证不足漏洞允许恶意绕过该保护，并且会再次触发通过脚本事件处理程序对 LibreLogo 的调用。此问题影响以下版本：6.2.6 之前的 Document Foundation LibreOffice 版本。(CVE-2019-9850)
- LibreOffice 通常与 LibreLogo 捆绑，后者是可编程的 turtle 向量图形脚本，可执行启动该脚本的文档中包含的任意 python 命令。已添加保护以解决 CVE-2019-9848，进而阻止通过文档事件处理程序（例如鼠标悬停）调用 LibreLogo。
但 LibreOffice 还有一项功能，即其中的文档可以指定可在各种全局文档脚本事件（例如 document-open 等）上执行的预安装脚本。在已修复的版本中，全局脚本事件处理程序经过验证，与文档脚本事件处理程序具有同等有效性。此问题影响以下版本：
6.2.6 之前的 Document Foundation LibreOffice 版本。(CVE-2019-9851)
- LibreOffice 具有一项功能，即其中的文档可以指定可在各种脚本事件（例如 mouse-over、document-open 等）上执行的预安装宏。预计只可以访问安装于 LibreOffice 的 share/Scripts/python 和 /user/Scripts/python 子目录下的脚本。已添加保护以解决 CVE-2019-9852，从而避免目录遍历攻击，此攻击可通过使用 URL 编码攻击破解路径验证步骤，进而在文件系统的任意位置执行脚本。但攻击者可利用 LibreOffice 直接通过传入路径的组件（而不是仅从路径验证步骤已审查的输出）组装最终脚本 URL 位置的方式中的缺陷绕过保护。此问题影响以下版本：6.2.7 之前的 Document Foundation LibreOffice 6.2 版本；6.3.1 之前的 6.3 版本。(CVE-2019-9854)
- LibreOffice 具有一项功能，即其中的文档可以指定可在各种脚本事件（例如 mouse-over、document-open 等）上执行的预安装宏。预计只可以访问安装于 LibreOffice 的 share/Scripts/python 和 /user/Scripts/python 子目录下的脚本。已添加保护以解决 CVE-2018-16858，从而避免目录遍历攻击，即在文件系统的任意位置执行脚本。但是，URL 编码攻击可能会绕过这项新保护。已修复的版本对描述脚本位置的解析 URL 进行了正确编码，以便随后继续处理。此问题影响以下版本：6.2.6 之前的 Document Foundation LibreOffice 版本。
(CVE-2019-9852)
- LibreOffice 文档可包含宏。这些宏的执行方式由文档安全设置控制，通常是在默认情况下阻断宏的执行。处理和分类文档内宏的 URL 的方式中存在一个 URL 解码缺陷，可能会导致构建文档以便宏执行绕过安全设置。已正确检测到这些文档包含宏，并提示用户文档中存在宏，但文档中的宏随后不受安全设置的控制，从而允许执行任意宏。此问题影响：6.2.7 之前的 LibreOffice 6.2 系列；
6.3.1 之前的 LibreOffice 6.3 系列。(CVE-2019-9853)
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。
