重点漏洞简述
根据产品流行度和漏洞重要性筛选出此次更新中包含影响较大的漏洞，请相关用户重点进行关注：
- CVE-2020-1054（PoC已公开）/CVE-2020-1143：Win32k 特权提升漏洞
由于Windows kernel-mode driver未能正确处理内存中的对象，导致存在两个特权提升漏洞。攻击者可通过登录目标系统并运行特制的应用程序来进行利用，成功利用此漏洞的攻击者可以在系统内核模式中执行任意代码。

- CVE-2020-1023、CVE-2020-1024、CVE-2020–1102和CVE-2020-1069：Microsoft SharePoint 远程执行代码漏洞
以上4个为微软SharePoint中的远程代码执行漏洞。攻击者可以利用此类漏洞获得在受影响终端或服务器上执行任意代码的能力。由于SharePoint无法检查应用程序包的源标记，前3个漏洞可以诱导用户打开一个特别制作的SharePoint应用程序文件从而进行利用。由于SharePoint Server无法正确识别和筛选不安全的 ASP.NET Web 控件，经过身份验证的攻击者通过上传一个特别制作的页面到SharePoint服务器，可成功利用CVE-2020-1069漏洞。
