# Ghostscript: crafted PostScript or PDF escapes -dSAFER and runs code

Link for people: https://infrastack.ai/live/CVE-2026-125396 (this .md is for agents)

Ghostscript before 10.08.0 has a -dSAFER bypass in the .putgstringcopy procedure, which calls the privileged .forceput operator without checking operand types. A crafted PostScript or PDF file can trigger a use-after-free across save/restore and execute arbitrary code.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Run `gs --version` on each host or container that renders PostScript or PDF files, and compare against `10.08.0`.
- Look for Ghostscript in image builds, document converters and PDF pipelines, since it is often bundled as a dependency.

## Fix

- Ghostscript: move to `10.08.0` or later.

## From the sources

Ghostscript before 10.08.0 contains a -dSAFER bypass vulnerability in the .putgstringcopy procedure in gs_fonts.ps, which calls the privileged .forceput operator without checking operand types. Attackers can supply crafted PostScript or PDF documents that trigger a type error, recover .forceput via a custom error handler, and cause a use-after-free across save/restore to execute arbitrary code.
