-Subject: [PATCH 3/5] Fix Bug 699660 "shading_param incomplete type checking"
-
-Its possible to pass a t_struct parameter to .shfill which is not a
-shading function built by .buildshading. This could then lead to memory
-corruption or a segmentation fault by treating the object passed in
-as if it were a shading.
-
-Its non-trivial to check the t_struct, because this function can take
-7 different kinds of structures as a parameter. Checking these is
-possible, of course, but would add a performance penalty.
-
-However, we can note that we never call .shfill without first calling
-.buildshading, and we never call .buildshading without immediately
-calling .shfill. So we can treat these as an atomic operation. The
-.buildshading function takes all its parameters as PostScript objects
-and validates them, so that should be safe.
-
-This allows us to 'hide' the .shfill operator preventing the possibility
-of passing an invalid parameter.
-
-CVE: CVE-2018-15909
-Upstream-Status: Backport [git://git.ghostscript.com/ghostpdl.git]
