Summary

A vulnerability in Artifex Ghostscript allows for remote code execution through specially crafted PostScript documents. This issue arises from the ability to switch to the IJS device or modify the IjsServer parameter after the SAFER security mechanism has been activated. The configuration permits the IJS server to be specified via the command line, which could lead to the execution of arbitrary commands if exploited. Users of Ghostscript versions 10.01.2 and earlier are particularly at risk due to this flaw.

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
