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.
Affected configurations
• artifex ghostscript (<= 9.25)
• debian debian linux 8.0
• redhat enterprise linux desktop 7.0
• redhat enterprise linux server 7.0
• redhat enterprise linux server aus 7.6
• redhat enterprise linux server eus 7.6
• redhat enterprise linux workstation 7.0
