Denial of service in ASP.NET Core
A denial of service vulnerability exists when ASP.NET Core improperly handles web requests, aka 'ASP.NET Core Denial of Service Vulnerability'.

Cookie parsing failure
A security feature bypass vulnerability exists in the way Microsoft ASP.NET Core parses encoded cookie names.The ASP.NET Core cookie parser decodes entire cookie strings which could allow a malicious attacker to set a second cookie with the name being percent encoded.The security update addresses the vulnerability by fixing the way the ASP.NET Core cookie parser handles encoded names., aka 'Microsoft ASP.NET Core Security Feature Bypass Vulnerability'.

Duplicate Advisory: .NET Information Disclosure Vulnerability
# Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-vh55-786g-wjwj. This link is maintained to preserve external references.

# Original Description
Microsoft is releasing this security advisory to provide information about a vulnerability in .NET Core 3.1 and .NET 6.0.  An information disclosure vulnerability exists in .NET Core 3.1 and .NET 6.0 that could lead to unauthorized access of privileged information.

## Affected software

* Any .NET 6.0 application running on .NET 6.0.7 or earlier.
* Any .NET Core 3.1 applicaiton running on .NET Core 3.1.27 or earlier.

## Patches

* If you're using .NET 6.0, you should download and install Runtime 6.0.8 or SDK 6.0.108 (for Visual Studio 2022 v17.1) from https://dotnet.microsoft.com/download/dotnet-core/6.0.
* If you're using .NET Core 3.1, you should download and install Runtime 3.1.28 (for Visual Studio 2019 v16.9) from https://dotnet.microsoft.com/download/dotnet-core/3.1.

ASP.NET Core and Visual Studio Denial of Service Vulnerability
A denial-of-service vulnerability exists in the way Kestrel parses HTTP/2 requests. The security update addresses the vulnerability by fixing the way the Kestrel parses HTTP/2 requests. Users are advised to upgrade.

.NET Denial of Service Vulnerability
Microsoft is releasing this security advisory to provide information about a vulnerability in .NET Core 3.1 and .NET 6.0. This advisory also provides guidance on what developers can do to update their applications to remove this vulnerability.

A denial of service vulnerability exists in ASP.NET Core 3.1 and .NET 6.0 where a malicious client could cause a stack overflow which may result in a denial of service attack when an attacker sends a customized payload that is parsed during model binding.

## <a name="affected-software"></a>Affected software
* Any .NET 6.0 application running on .NET 6.0.8 or earlier.
* Any ASP.NET Core 3.1 application running on .NET Core 3.1.28 or earlier.
If your application uses the following package versions, ensure you update to the latest version of .NET.
