## Advisory FAQ
### <a name="how-affected"></a>How do I know if I am affected?
If using an affected package listed in [affected products](#affected-products) or [affected packages](#affected-packages), you're exposed to the vulnerability.
### <a name="how-fix"></a>How do I fix the issue?
1. To fix the issue please install the latest version of .NET 8.0, NET 9.0, or .NET 10.0, as appropriate. 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.
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.
