With Visual Studio 2017 version 15.7 Preview 3 we have two new features to announce with regards to our Spectre mitigations. First, the /Qspectre switch is now supported regardless of the selected optimization level. Second, we have provided Spectre-mitigated implementations of the Microso...
All versions of Visual Studio 2017 version 15.5 and all Previews of Visual Studio version 15.6 already include an undocumented switch,/d2guardspecload, that is currently equivalent to/Qspectre. You can use/d2guardspecloadto apply the same mitigations to your code. Please update to using/Qspec...
如需詳細資訊,請參閱官方Microsoft安全性諮詢ADV180002,以減輕推測性執行端通道弱點的指引。 您可以從 Intel 的推測性執行旁路攻擊風險降低 (Speculative Execution Side Channel Mitigations)和 ARM 的快取推測性旁路攻擊 (Cache Speculation Side-channels)中取得指導方針。
从Visual Studio 2017 版本 15.5.5 开始提供/Qspectre选项,在 2018 年 1 月 23 日及之后对 Microsoft C/C++ 编译器 (MSVC) 做出的所有更新中均提供该选项。 使用 Visual Studio 安装程序更新编译器并安装 Spectre 缓解库作为单独组件。 此外,Visual Studio 2015 Update 3 通过一个修补程序提供/Qspectre选项。
Would you make use of a /Qspectre variant that provides the most secure mitigation assistance -- at the cost of a significant performance loss? (The Visual Studio team can be reachedonlineor byemail.) In my opinion, the best approach is to address the security issue fully when a developer...
我这里Google到的解决办法是把 "C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Common7\IDE\VC\VCTargets\Platforms\($PLATFORM)\ImportBefore\Default\Microsoft.Cpp.WDK.props" 文件中的 <PropertyGroup> <SpectreMitigation Condition="'$(SpectreMitigation)' == ''">Spectre</SpectreMitigation...
For ease of use, we are also providing copies of most libraries in the Spectre library directories. However, they are not all Spectre-mitigated. The following table specifies which libraries are mitigated. Note also that the files that have Spectre mitigations should...

Applying this update will enable the Spectre Variant 2 mitigation CVE-2017-5715 - “Branch target injection vulnerability.” Advanced users can also manually enable mitigation against Spectre, Variant 2 through the registry settings documented in the following articles: ...
Windows Server on any silicon, especially in any IO-intensive application, shows a more significant performance impact when you enable the mitigations to isolate untrusted code within a Windows Server instance. This is why you want to be careful to evaluate ...
