Описание
An issue was discovered in Artifex Ghostscript before 9.24. A type confusion in "ztype" could be used by remote attackers able to supply crafted PostScript to crash the interpreter or possibly have unspecified other impact.
It was discovered that the ghostscript .type operator did not properly validate its operands. A specially crafted PostScript document could exploit this to crash ghostscript or, possibly, execute arbitrary code in the context of the ghostscript process.
