CVE-2026-110133

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

Published Oct 30, 2026 CVSS 3.1 · 5.8 Medium EPSS < 1% KEV · Not listed
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.

Remediation

Vendor Workaround

To mitigate this issue, avoid processing untrusted documents or standalone TrueType fonts with Ghostscript. If feasible, disable TrueType instruction execution within Ghostscript configurations. Consult Ghostscript documentation for specific configuration options to disable TrueType instruction execution. Running Ghostscript in a restrictive sandbox environment can also reduce the blast radius of potential exploitation.
