Описание
In Artifex Ghostscript before 9.24, attackers able to supply crafted PostScript files could use incorrect free logic in pagedevice replacement to crash the interpreter.
It was discovered that the ghostscript device cleanup did not properly handle devices replaced with a null device. An attacker could possibly exploit this to bypass the -dSAFER protection and crash ghostscript or, possibly, execute arbitrary code in the ghostscript context via a specially crafted PostScript document.
