Vulnerability in ImageSharp dependency

[madorjan]

The currently used SixLabors.ImageSharp version has a vulnerability, which produces following compiler warning:
NU1903 Warning As Error: Package 'SixLabors.ImageSharp' 2.1.6 has a known high severity vulnerability, https://github.com/advisories/GHSA-65x7-c272-7g7r

SixLabors.ImageSharp should be updated to 3.1.3.

ImageSharp 3 has a less permissive license requiring payment for commercial projects IIRC. I'm not sure if this is an option for commercial projects using Aardvark.

According to the license text, indirect usage of ImageSharp falls under the Apache 2.0 license. If I understand this correctly, for commercial Aardvark users that don't use ImageSharp directly, no license changes should happen.

That's how I understand it as well. Back then we had some concerns, but I don't remember the details. It's probably fine as it is worded.

Apparently, they backported the fix and released 2.1.7. You should be able to use that without requiring a new Aardvark.Base version. Still, it might be a good idea to move to 3.X eventually.

Edit: ImageSharp 3.X only supports .NET >= 6

OK, then I think an update to 2.1.7 would bei sufficient 👍
