Description

The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists in gdevijs.c in GhostPDL due to the way PostScript handles IJS device change. A remote attacker can trick the victim to open a specially crafted document that will switch to the IJS device, start the IJS server and execute arbitrary commands on the system.
