NVD Description

Note: Versions mentioned in the description apply only to the upstream ghostscript-cups package and not the ghostscript-cups package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

In Artifex Ghostscript through 9.25, the setpattern operator did not properly validate certain types. A specially crafted PostScript document could exploit this to crash Ghostscript or, possibly, execute arbitrary code in the context of the Ghostscript process. This is a type confusion issue because of failure to check whether the Implementation of a pattern dictionary was a structure type.
