![]() ![]() If your code operates on data that crosses a trust boundary, then we recommend you use the /Qspectre option to rebuild and redeploy your code to mitigate this issue as soon as possible. App-local deployment of such libraries isn't possible. There are no versions of Spectre-mitigated libraries for Universal Windows (UWP) apps or components. ![]() They're found in the Individual Components tab under SDKs, libraries, and frameworks. You can also install Spectre-mitigated libraries for MFC and ATL. The contents of the Visual C++ Runtime Libraries Redistributable haven't been modified. The DLLs are supported for application-local deployment only. Both DLL and static runtime libraries with mitigation enabled are available for a subset of the Visual C++ runtimes: VC++ start-up code, vcruntime140, msvcp140, concrt140, and vcamp140. They're found in the Individual Components tab under Compilers, build tools, and runtimes, and have "Libs for Spectre" in the name. The Spectre-mitigated libraries for Visual Studio can be downloaded in the Visual Studio Installer. ![]() Several Microsoft C++ libraries are also available in versions with Spectre mitigation. Starting in Visual Studio 2017 version 15.7, the /Qspectre option is supported at all optimization levels. In its initial release, the /Qspectre option only worked on optimized code. It's available in Visual Studio 2015 Update 3 through KB 4338871. The /Qspectre option is available starting in Visual Studio 2017 version 15.5.5 and all later versions. They affect many operating systems and modern processors, including processors from Intel, AMD, and ARM. These vulnerabilities are called speculative execution side-channel attacks. The /Qspectre option causes the compiler to insert instructions to mitigate certain Spectre security vulnerabilities. Specifies compiler generation of instructions to mitigate certain Spectre variant 1 security vulnerabilities. ![]()
