Record from redhat · Published October 2, 2026

A flaw was found in Ghostscript. This heap-based buffer overflow vulnerability in the JPEG 2000 output adapter allows an attacker to cause memory corruption by supplying a specially crafted PDF file. The crafted PDF contains a JPEG 2000 image with mismatched component subsampling factors. Successful exploitation could lead to arbitrary code execution.
