This advisory also provides guidance on what developers can do to update their applications to remove this vulnerability. System.Security.Cryptography.Cose, System.IO.Packaging, Microsoft.Extensions.Caching.Memory may be exposed to a hostile input which may lead them to be susceptible to hash flooding attacks resulting in denial of service. ## Announcement Announcement for this issue can be found at https://github.com/dotnet/announcements/issues/327 ## <a name="mitigation-factors"></a>Mitigation factors Microsoft has not identified any mitigating factors for this vulnerability. ## <a name="affected-software"></a>Affected software * Any .NET 8.0 application running on .NET 8.0.8 or earlier. * Any .NET 6.0 aplication running on .NET 6.0.33 or earlier. * Any application consuming one of the [vulnerable packages](affected-packages). ## <a name="affected-packages"></a>Affected Packages * Any .NET 6.0, 8.0, or 9.0 application. * Any application consuming one of the vulnerable packages. ### <a name=".NET 9 "></a>.NET 9 Package name | Affected version | Patched version ------------ | ---------------- | ------------------------- [System.Security.Cryptography.Cose](https://www.nuget.org/packages/System.Security.Cryptography.Cose) | >= 9.0.0-preview.1.24080.9, <= 9.0.0-rc.1.24431.7 | 9.0.0-rc.2.24473.5 [System.IO.Packaging](https://www.nuget.org/packages/System.IO.Packaging) | >= 9.0.0-preview.1.24080.9, <= 9.0.0-rc.1.24431.7 | 9.0.0-rc.2.24473.5 [Microsoft.Extensions.Caching.Memory](https://www.nuget.org/packages/Microsoft.Extensions.Caching.Memory) | >= 9.0.0-preview.1.24080.9, <= 9.0.0-rc.1.24431.7 | 9.0.0-rc.2.24473.5 ### <a name=".NET 8"></a>.NET 8 Package name | Affected version | Patched version ------------ | ---------------- | ------------------------- [System.Security.Cryptography.Cose](https://www.nuget.org/packages/System.Security.Cryptography.Cose) | >= 8.0.0-preview.1.23110.8, <= 8.0.0 | 8.0.1 [System.IO.Packaging](https://www.nuget.org/packages/System.IO.Packaging) | >= 8.0.0-preview.1.23110.8, <= 8.0.0 | 8.0.1 [Microsoft.Extensions.Caching.Memory](https://www.nuget.org/packages/Microsoft.Extensions.Caching.Memory) | >= 8.0.0-preview.1.23110.8, <= 8.0.0 | 8.0.1 ### <a name=".NET 6"></a>.NET 6 Package name | Affected version | Patched version ------------ | ---------------- | ------------------------- [System.IO.Packaging](https://www.nuget.org/packages/System.IO.Packaging) | >= 6.0.0-preview.1.21102.12, <= 6.0.0 | 6.0.1 [Microsoft.Extensions.Caching.Memory](https://www.nuget.org/packages/Microsoft.Extensions.Caching.Memory) | >=6.0.0-preview.1.21102.12 <= 6.0.1 | 6.0.2 ## Advisory FAQ ### <a name="how-affected"></a>How do I know if I am affected? If you have a runtime or SDK with a version listed, or an affected package listed in [affected software](#affected-packages) or [affected packages](#affected-software), you're exposed to the vulnerability. ### <a name="how-fix"></a>How do I fix the issue? * To fix the issue please install the latest version of .NET 8.0 or .NET 6.0. If you have installed one or more .NET SDKs through Visual Studio, Visual Studio will prompt you to update Visual Studio, which will also update your .NET SDKs. * .NET Framework-based applications and other application types need to perform a package update. * If you have .NET 6.0 or greater installed, you can list the versions you have installed by running the `dotnet --info` command. You will see output like the following; ``` .NET Core SDK (reflecting any global.json): Version: 8.0.200 Commit: 8473146e7d Runtime Environment: OS Name: Windows OS Version: 10.0.18363 OS Platform: Windows RID: win10-x64 Base Path: C:\Program Files\dotnet\sdk\6.0.300\ Host (useful for support): Version: 8.0.3 Commit: 8473146e7d .NET Core SDKs installed: 8.0.200 [C:\Program Files\dotnet\sdk] .NET Core runtimes installed: Microsoft.AspAspNetCore.App 8.0.3 [C:\Program Files\dotnet\shared\Microsoft.AspAspNetCore.App] Microsoft.AspNetCore.App 8.0.3 [C:\Program Files\dotnet\shared\Microsoft.AspNetCore.App] Microsoft.WindowsDesktop.App 8.0.3 [C:\Program Files\dotnet\shared\Microsoft.WindowsDesktop.App] To install additional .NET Core runtimes or SDKs: https://aka.ms/dotnet-download ``` * If you're using .NET 9.0, you should download and install .NET 9.0 RC 2 Runtime or .NET 9.0.100-rc.2.24474.11 SDK (for Visual Studio 2022 v17.12 latest Preview) from https://dotnet.microsoft.com/download/dotnet-core/9.0. * If you're using .NET 8.0, you should download and install .NET 8.0.10 Runtime or .NET 8.0.110 SDK (for Visual Studio 2022 v17.8) from https://dotnet.microsoft.com/download/dotnet-core/8.0. * If you're using .NET 6.0, you should download and install .NET 6.0.35 Runtime or .NET 6.0.135 SDK (for Visual Studio 2022 v17.6) from https://dotnet.microsoft.com/download/dotnet-core/6.0. .NET 6.0 and .NET 8.0 updates are also available from Microsoft Update. To access this either type "Check for updates" in your Windows search, or open Settings, choose Update & Security and then click Check for Updates.
