Wordfence researchers using their Argus AI system found a critical heap buffer overflow in Ghostscript, the PostScript/PDF rendering engine used by tools like ImageMagick and WordPress's thumbnail generator. A malicious PDF embedding a JPEG 2000 image can force Ghostscript to write far more data than a buffer can hold, corrupting memory and allowing unauthenticated remote code execution. The bug affects Ghostscript versions 9.21 through 10.07.1 and was confirmed present across ten tested Linux distributions and an official WordPress Docker image.
