Name of the Vulnerable Software and Affected Versions ImageSharp versions prior to 2.1.7 ImageSharp versions prior to 3.1.3

Description A heap-use-after-free flaw was found in ImageSharp's InitializeImage() function of PngDecoderCore.cs file. This issue is triggered when an attacker passes a specially crafted PNG image file to ImageSharp for conversion, potentially leading to information disclosure.

Recommendations For versions prior to 2.1.7, upgrade to version 2.1.7 to resolve the issue. For versions prior to 3.1.3, upgrade to version 3.1.3 to resolve the issue. As a temporary workaround, consider avoiding the use of the InitializeImage() function in the PngDecoderCore.cs file until a patch is applied.
