-Subject: [PATCH 1/5] Bug 699795: add operand checking to
- .setnativefontmapbuilt
-
-.setnativefontmapbuilt .forceputs a value into systemdict - it is intended
-to be a boolean, but in this case was being called with a compound object
-(a dictionary). Such an object, in local VM, being forced into systemdict
-would then confuse the garbager, since it could be restored away with the
-reference remaining.
-
-This adds operand checking, so .setnativefontmapbuilt will simply ignore
-anything other than a boolean value, and also removes the definition of
-.setnativefontmapbuilt after use, since it is only used in two, closely
-related places.
-

-Subject: [PATCH 2/5] Bug 699816: Improve hiding of security critical custom
- operators
-
-Make procedures that use .forceput/.forcedef/.forceundef into operators.
-
-The result of this is that errors get reported against the "top" operator,
-rather than the "called" operator within the procedure.
-
-For example:
-/myproc
-{
- myop
-} bind def
-
-If 'myop' throws an error, the error handler will be passed the 'myop'
-operator. Promoting 'myproc' to a operator means the error handler will be
-passed 'myproc'.

-Subject: [PATCH 3/5] Bug 699832: add control over hiding error handlers.
-
-With a previous commit changing error handling in SAFER so the handler gets
-passed a name object (rather than executable object), it is less critical to
-hide the error handlers.
-
-This introduces a -dSAFERERRORS option to force only use of the default error
-handlers.
-
-It also adds a .setsafererrors Postscript call, meaning a caller, without
--dSAFERERRORS, can create their own default error handlers (in errordict, as
-normal), and then call .setsafererrors meaning their own handlers are always
-called.
-
-With -dSAFERERRORS or after a call to .setsafererrors, .setsafererrors is
-removed.
-
-CVE: CVE-2018-17961
-Upstream-Status: Backport [git://git.ghostscript.com/ghostpdl.git]

-Subject: [PATCH 4/5] For hidden operators, pass a name object to error
- handler.
-
-In normal operation, Postscript error handlers are passed the object which
-triggered the error: this is invariably an operator object.
-
-The issue arises when an error is triggered by an operator which is for internal
-use only, and that operator is then passed to the error handler, meaning it
-becomes visible to the error handler code.
-
-By converting to a name object, the error message is still valid, but we no
-longer expose internal use only operators.
-
-The change in gs_dps1.ps is related to the above: previously an error in
-scheck would throw an error against .gcheck, but as .gcheck is now a hidden
-operator, it resulted in a name object being passed to the error handler. As
-scheck is a 'real' operator, it's better to use the real operator, rather than
-the name of an internal, hidden one.
