RHSA-2026:76877 PUBLISHED CVSS 7.800000190734863 HIGH

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.
