Overview

Affected versions of this package are vulnerable to Out-of-bounds Write in the PSD decoding process due to a mismatch between the computed bytes-per-pixel from the image header and the allocated pixel buffer size in LAB 16-bit mode. An attacker can achieve arbitrary code execution or cause a denial of service by supplying a crafted PSD file that triggers a heap buffer overflow during image processing.
