## Advisory FAQ

### 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-software) or [affected packages](#affected-packages), you're exposed to the vulnerability.

### How do I fix the issue?

1. To fix the issue please install the latest version of .NET 9.0. 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.
2. If your application references the vulnerable package, update the package reference to the patched version.

* You can list the versions you have installed by running the `dotnet --info` command. You will see output like the following:

* If you're using .NET 9.0, you should download and install .NET 9.0.3 Runtime or .NET 9.0.103 SDK (for Visual Studio 2022 v17.12 latest Preview) from https://dotnet.microsoft.com/download/dotnet-core/9.0.

Once you have installed the updated runtime or SDK, restart your apps for the update to take effect.

Additionally, if you've deployed [self-contained applications](https://docs.microsoft.com/dotnet/core/deploying/#self-contained-deployments-scd) targeting any of the impacted versions, these applications are also vulnerable and must be recompiled and redeployed.
