综述
微软于周二发布了7月安全更新补丁，修复了124个从简单的欺骗攻击到远程代码执行的安全问题，产品涉及.NET Framework、Azure DevOps、Internet Explorer、Microsoft Edge、Microsoft Graphics Component、Microsoft JET Database Engine、Microsoft Malware Protection Engine、Microsoft Office、Microsoft Office SharePoint、Microsoft OneDrive、Microsoft Scripting Engine、Microsoft Windows、Open Source Software、Skype for Business、Visual Studio、Windows Hyper-V、Windows IIS、Windows Kernel、Windows Shell、Windows Subsystem for Linux、Windows Update Stack以及Windows WalletService。
Critical & Important漏洞概述
本次微软共修复了16个Critical级别漏洞，104 个 Important 级别漏洞，虽然本月公布的漏洞暂未发现公开利用的情况，仍强烈建议所有用户尽快安装更新：
Windows DNS服务器远程代码执行漏洞SigRed（CVE-2020-1350）
本月修复的最严重漏洞是一个存在于Windows DNS 服务器中的可蠕虫化漏洞CVE-2020-1350（代号 SigRed）。
微软官方给出的评分为 10 分（CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:P/RL:O/RC:C）。
未经身份验证的攻击者通过向受影响服务器发送精心构造的请求数据包来利用该漏洞，成功的利用可实现在目标系统上执行任意代码。

Hyper-V RemoteFX vGPU 远程代码执行漏洞（CVE-2020-1041， CVE-2020-1040，CVE-2020-1032， CVE-2020-1036，CVE-2020-1042， CVE-2020-1043）
由于宿主机（Host）上的Hyper-V RemoteFX vGPU无法正确验证客户机（Guest）上经过身份验证用户的输入，存在一个远程代码执行漏洞。利用此漏洞时，攻击者可以在客户机上运行经特殊设计的应用程序，从而攻击在Hyper-V宿主机上运行的某些第三方视频驱动程序，最终实现在宿主机操作系统上执行任意代码。
官方未针对以上漏洞提供补丁程序，并就为什么禁用和删除RemoteFX而不修复漏洞进行了答复：
在2019年10月，微软宣布将停止Remote FX的开发并创建新功能。对于Windows 10 1809及更高版本以及Windows Server 2019，不再支持RemoteFX vGPU。由于这些漏洞本质上是体系结构的问题，并且该功能已在较新版本的Windows中弃用，因此Microsoft确定禁用和删除RemoteFX是更好的做法。
