<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, 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 6.0 or .NET 7.0. 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. If you are using one of the affected packages, please update to the patched version listed above. 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;

Version 1.0
Last Updated 2023-09-12
.NET, .NET Framework, and Visual Studio Elevation of Privilege Vulnerability
Visual Studio Denial of Service Vulnerability
ASP.NET Security Feature Bypass Vulnerability
.NET Framework Denial of Service Vulnerability
Information Disclosure: MD.SqlClient(MDS) & System.data.SQLClient (SDS) - client library supports establishing non-ssl TCP connection
Description Microsoft is releasing this security advisory to provide information about a vulnerability in .NET 6.0, .NET 7.0 and .NET 8.0. This advisory also provides guidance on what developers can do to update their applications to address this vulnerability.
A security feature bypass vulnerability exists when Microsoft .NET Framework-based applications use X.509 chain building APIs but do not completely validate the X.509 certificate due to a logic flaw. An attacker could present an arbitrary untrusted certificate with malformed signatures, triggering a bug in the framework. The framework will correctly report that X.509 chain building failed, but it will return an incorrect reason code for the failure. Applications which utilize this reason code to make their own chain building trust decisions may inadvertently treat this scenario as a successful chain build. This could allow an adversary to subvert the app's typical authentication logic.
Affected software NuGet & NuGet Packages - Any NuGet.exe, NuGet.CommandLine, NuGet.Packaging 6.8.0 version or earlier. - Any NuGet.exe, NuGet.CommandLine, NuGet.Packaging 6.7.0 version or earlier. - Any NuGet.exe, NuGet.CommandLine, NuGet.Packaging 6.6.1 version or earlier. - Any NuGet.exe, NuGet.CommandLine, NuGet.Packaging 6.4.2 version or earlier. - Any NuGet.exe, NuGet.CommandLine, NuGet.Packaging 6.3.3 version or earlier. - Any NuGet.exe, NuGet.CommandLine, NuGet.Packaging 6.0.5 version or earlier. - Any NuGet.exe, NuGet.CommandLine, NuGet.Packaging 5.11.5 version or earlier.

.NET, .NET Framework, and Visual Studio Remote Code Execution Vulnerability
.NET Framework Remote Code Execution Vulnerability.
.NET Kestrel: Denial of Service processing X509 Certificates
When a .NET application is internet-facing and accepts an X509 client certificate for mutual TLS, a malicious client certificate can cause unbounded CPU usage.
Microsoft .NET Framework 3.0 SP2, 3.5, 3.5.1, 4, and 4.5; Silverlight 5 before 5.1.20513.0; win32k.sys in the kernel-mode drivers, and GDI+, DirectWrite, and Journal, in Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8, Windows Server 2012, and Windows RT; GDI+ in Office 2003 SP3, 2007 SP3, and 2010 SP1; GDI+ in Visual Studio .NET 2003 SP1; and GDI+ in Lync 2010, 2010 Attendee, 2013, and Basic 2013 allow remote attackers to execute arbitrary code via a crafted TrueType Font (TTF) file, aka "TrueType Font Parsing Vulnerability."

The JIT compiler in Microsoft .NET Framework 3.5 Gold and SP1, 3.5.1, and 4.0, when IsJITOptimizerDisabled is false, does not properly handle expressions related to null strings, which allows context-dependent attackers to bypass intended access restrictions, and consequently execute arbitrary code, in opportunistic circumstances by leveraging a crafted application, as demonstrated by (1) a crafted XAML browser application (aka XBAP), (2) a crafted ASP.NET application, or (3) a crafted .NET Framework application, aka ".NET Framework JIT Optimization Vulnerability."
Microsoft .NET Framework 2.0 SP2, 3.0 SP2, 3.5, 3.5.1, 4.5.2, 4.6, 4.6.1, 4.6.2, 4.7, 4.7.1, .NET Core 1.0 and 2.0, and PowerShell Core 6.0.0 allow a security feature bypass vulnerability due to the way certificates are validated, aka ".NET Security Feature Bypass Vulnerability."
The Common Language Runtime (CLR) in Microsoft .NET Framework 2.0, 2.0 SP1, 2.0 SP2, 3.5, and 3.5 SP1, and Silverlight 2, does not properly handle interfaces, which allows remote attackers to execute arbitrary code via (1) a crafted XAML browser application (XBAP), (2) a crafted Silverlight application, (3) a crafted ASP.NET application, or (4) a crafted .NET Framework application, aka "Microsoft Silverlight and Microsoft .NET Framework CLR Vulnerability."
ASP.NET in Microsoft .NET Framework 2.0 SP1 and SP2 and 3.5 Gold and SP1, when ASP 2.0 is used in integrated mode on IIS 7.0, does not properly manage request scheduling, which allows remote attackers to cause a denial of service (daemon outage) via a series of crafted HTTP requests, aka "Remote Unauthenticated Denial of Service in ASP.NET Vulnerability."
Microsoft .NET Framework 1.1 SP1, 2.0 SP1 and SP2, 3.5, 3.5 SP1, 3.5.1, and 4.0, as used for ASP.NET in Microsoft Internet Information Services (IIS), provides detailed error codes during decryption attempts, which allows remote attackers to decrypt and modify encrypted View State (aka VIEWSTATE) form data, and possibly forge cookies or read application files, via a padding oracle attack, aka "ASP.NET Padding Oracle Vulnerability."
The Common Language Runtime (CLR) in Microsoft .NET Framework 2.0 SP1, 2.0 SP2, 3.5, 3.5 SP1, and 3.5.1, and Microsoft Silverlight 2 and 3 before 3.0.50611.0 on Windows and before 3.0.41130.0 on Mac OS X, does not properly handle interfaces and delegations to virtual methods, which allows remote attackers to execute arbitrary code via (1) a crafted XAML browser application (aka XBAP), (2) a crafted ASP.NET application, or (3) a crafted .NET Framework application, aka "Microsoft Silverlight and Microsoft .NET Framework CLR Virtual Method Delegate Vulnerability."
Microsoft .NET Framework 2.0 SP1 and SP2, 3.5 Gold and SP1, 3.5.1, and 4.0, and Silverlight 4 before 4.0.60531.0, does not properly validate arguments to unspecified networking API functions, which allows remote attackers to execute arbitrary code via (1) a crafted XAML browser application (aka XBAP), (2) a crafted ASP.NET application, (3) a crafted .NET Framework application, or (4) a crafted Silverlight application, aka ".NET Framework Array Offset Vulnerability."
