  "description": "SAIL is a cross-platform library for loading and saving images with support for animation, metadata, and ICC profiles. Prior to commit c930284445ea3ff94451ccd7a57c999eca3bc979, the PSD codec computes bytes-per-pixel (\u0060bpp\u0060) from raw header fields \u0060channels * depth\u0060, but the pixel buffer is allocated based on the resolved pixel format. For LAB mode with \u0060channels=3, depth=16\u0060, \u0060bpp = (3*16\u002B7)/8 = 6\u0060, but the format \u0060BPP40_CIE_LAB\u0060 allocates only 5 bytes per pixel. Every pixel write overshoots, causing a deterministic heap buffer overflow on every row. Commit c930284445ea3ff94451ccd7a57c999eca3bc979 contains a patch.",
