Overview
Affected versions of this package are vulnerable to Out-of-bounds Read via the png_write_image_8bit function, which incorrectly processes 8-bit image data as 16-bit when the simplified write API is used with convert_to_8bit enabled. An attacker can craft a malicious 8-bit PNG image, causing it to over-read the heap buffer.
