What is CVE-2026-110133?

A vulnerability in Ghostscript allows remote attackers to exploit a flaw during TrueType font processing. When opening a maliciously crafted document that contains a specially designed font, an attacker can bypass buffer size validations through an accounting error in font rendering. This could potentially lead to a Denial of Service (DoS) or facilitate arbitrary code execution, posing a serious risk to users and automated services.
