Описание
In Artifex Ghostscript before 9.24, attackers able to supply crafted PostScript files could use a type confusion in the setcolor function to crash the interpreter or possibly have unspecified other impact.
It was discovered that the ghostscript did not properly validate the operands passed to the setcolor function. 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.
Отчет
This issue did not affect the versions of ghostscript as shipped with Red Hat Enterprise Linux 5, 6, and 7.
