Description
Ghostscript before 10.08.0 contains a -dSAFER bypass vulnerability in the .putgstringcopy procedure in gs_fonts.ps, which calls the privileged .forceput operator without checking operand types. Attackers can supply crafted PostScript or PDF documents that trigger a type error, recover .forceput via a custom error handler, and cause a use-after-free across save/restore to execute arbitrary code.
