Ghostscript: heap buffer overflow in ghostscript truetype outliner due to npointstotal integer underflow during retry rollback

Published Oct 30, 2026 · Updated Nov 5, 2026 · Assigned by redhat

Description

A flaw was found in Ghostscript. When processing a specially crafted TrueType font or document embedding one, an accounting error during font rendering can bypass buffer size checks, triggering a heap-based buffer overflow. A remote attacker could exploit this by enticing a victim or automated service to open the malicious content, potentially resulting in a Denial of Service (DoS) crash or arbitrary code execution.
