ImageSharp: ICC CLUT parsing allocates from unvalidated channel and grid dimensions
ImageSharp is a 2D graphics library. From 1.0.0-beta0001 until 4.1.2, ICC CLUT parsing calculates allocation sizes from attacker-declared channel and grid dimensions before confirming that the profile contains the declared values. IccDataReader.ReadClutF32 can request a large float array, and earlier public IccProfile.Entries parsing paths can allocate a large jagged representation, from a short truncated profile. In version 4, automatic image conversion reaches the parser when DecoderOptions.ColorProfileHandling is Convert; the default Preserve mode avoids that conversion path. The demonstrated impact is memory pressure and input-validation failure, not unhandled process termination. This issue is fixed in version 4.1.2.
