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.\n\n## Affected\n\n- `ghostscript (all versions)`\n- `ghostscript`\n- `ghostscript (all versions)`\n- `ghostscript (all versions)`\n- `ghostscript (all versions)`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n### Workarounds\n\nTo 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.","depth":"sunlit","depthScore":32,"depthScoreParts":{"impact":31.9,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
