dotnet6 vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

Ubuntu 22.04 LTS

Summary:

.NET 6 could be made to crash if it parsed a specially crafted file.

Software Description: - dotnet6: dotNET CLI tools and runtime

Details:

Graham Esau discovered that .NET 6 incorrectly parsed certain payloads during model binding. An attacker could possibly use this issue to cause a denial of service.

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 22.04 LTS: aspnetcore-runtime-6.0 6.0.109-0ubuntu1~22.04.1 dotnet-host 6.0.109-0ubuntu1~22.04.1 dotnet-hostfxr-6.0 6.0.109-0ubuntu1~22.04.1 dotnet-runtime-6.0 6.0.109-0ubuntu1~22.04.1 dotnet-sdk-6.0 6.0.109-0ubuntu1~22.04.1 dotnet6 6.0.109-0ubuntu1~22.04.1

In general, a standard system update will make all the necessary changes. A restart may be required after the update if any affected files are being used
