Overview
Affected versions of this package are vulnerable to Integer Overflow or Wraparound in the ConvertCbYCrYToRGB function. An attacker can cause a heap out-of-bounds write by supplying crafted image data that triggers a signed integer overflow in the pixel-loop index expression, potentially leading to process crashes or arbitrary code execution.
