[Pkg-gmagick-im-team] Bug#1036200: Malicious postscript code?

[Alexander Vivian Hugh McPhail]

/Y /setcmykcolor where { %%ifelse Use built-in operator
       /setcmykcolor get
   }{ %%ifelse Emulate setcmykcolor with setrgbcolor
       { %%def
           1 sub 3 { %%repeat
               3 index add neg dup 0 lt { pop 0 } if 3 1 roll
           } repeat setrgbcolor
       } bind

/stringbbox {gsave NP 0 0 m false charpath flattenpath
   pathbbox 4 2 roll pop pop 1.1 mul cvi exch 1.1 mul
   cvi exch grestore} def

Predefined untyped Y combinator appears to delete things until there is nothing left to delete.  Not sure.
