ghostscript: Type confusion in setpattern (700141)
Published Dec 20, 2018
7.8
HIGHCVSS 3.0
EPSS 2.87%
Description
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.
