Description

In Artifex Ghostscript 9.23 before 2018-08-24, a type confusion using the .shfill operator could be used by attackers able to supply crafted PostScript files to crash the interpreter or potentially execute code. It was discovered that the ghostscript .shfill operator did not properly validate certain types. 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.
