A flaw was found in all versions of ghostscript 9.x before 9.50, where the
.charkeys
procedure, where it did not properly secure its privileged
calls, enabling scripts to bypass -dSAFER
restrictions. An attacker could
abuse this flaw by creating a specially crafted PostScript file that could
escalate privileges within the Ghostscript and access files outside of
restricted areas or execute commands.
