Critical & Important漏洞概述
分 Critical 及Important 漏洞描述如下：
- Windows内核本地特权提升漏洞（CVE-2020-17087）
本月2号，Google Project Zero团队发布了一篇关于Windows cng.sys提权漏洞（CVE-2020-17087）的文章。该漏洞允许攻击者在未授权的情况下，通过诱使用户运行精心制作的恶意程序，达到权限提升的效果。当时CVE-2020-17087已经有在野利用的行为出现，并且微软官方没有发布相关补丁。
在本次更新中，该漏洞被修复。请受影响用户尽快安装补丁进行防护。
官方评级 Important，CVSS:3.0 7.8/7.2

- Windows网络文件系统（NFS）漏洞（CVE-2020-17051/ 17056）
CVE-2020-17051是一个存在于nfssvr.sys驱动中的远程代码执行漏洞，可导致蓝屏死机（BSOD）。
CVE-2020-17056是一个存在于nfssvr.sys驱动中的远程内核数据读取漏洞，可导致ASLR（地址空间布局随机化）被绕过。
当这两个漏洞被组合利用时，在Windows服务器上绕过漏洞缓解措施并实现远程利用的可能性大大增加。
NFS用于在Windows和Unix/Linux环境中做文件共享。
