Buffer overflow in Sixlabors Imagesharp

CVE-2026-106112

ImageSharp is a 2D graphics library. From 4.0.0 until 4.1.2, ICC LUT16 conversion accepts more than four output channels even though ClutCalculator.Calculate and LutEntryCalculator.CalculateLut store intermediate and output values in Vector4. When DecoderOptions.ColorProfileHandling is set to Convert, a malformed embedded profile can direct interpolation and output-LUT operations to write one float per declared channel beyond the four-float destination. This can corrupt memory and terminate the process; the default Preserve mode does not run ICC conversion. This issue is fixed in version 4.1.2.
