ImageSharp is a managed, cross-platform, 2D graphics library. A heap-use-after-free flaw was found in ImageSharp’s InitializeImage() function of PngDecoderCore.cs file. This vulnerability is triggered when an attacker passes a specially crafted PNG image file to ImageSharp for conversion, potentially leading to information disclosure. This issue has been patched in versions 3.1.3 and 2.1.7.
