+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

+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.

+Subject: [PATCH 2/2] Bug 699927: don't include operator arrays in execstack
+ output
+
+When we transfer the contents of the execution stack into the array, take the
+extra step of replacing any operator arrays on the stack with the operator
+that reference them.
+
+This prevents the contents of Postscript defined, internal only operators (those
+created with .makeoperator) being exposed via execstack (and thus, via error
+handling).
+
+This necessitates a change in the resource remapping 'resource', which contains
+a procedure which relies on the contents of the operators arrays being present.
+As we already had internal-only variants of countexecstack and execstack
+(.countexecstack and .execstack) - using those, and leaving thier operation
+including the operator arrays means the procedure continues to work correctly.
+
+Both .countexecstack and .execstack are undefined after initialization.
+
+Also, when we store the execstack (or part thereof) for an execstackoverflow
+error, make the same oparray/operator substitution as above for execstack.

+Subject: [PATCH] Make .forceput unavailable from '.policyprocs' helper
+ dictionary
+
+Bug #69963 "1Policy is a dangerous operator, any callers should be odef"
+
+Leaving the .policyprocs dictionary with a procedure which is a simple
+wrapper for .forceput effectively leaves .forceput available.
+
+It seems that the only reason to have .policyprocs is to minimise the
+code in .applypolicies, so we can remove the dictionary and put the
+code straight into .applypolicies, which we can then bind and make
+executeonly, which hides the .forceput. Also, since we don't need
+.applypolicies after startup, we can undefine that from systemdict too.
+
+While we're here, review all the uses of .force* to make certain that
+there are no other similar cases. This showed a few places where we
+hadn't made a function executeonly, so do that too. Its probably not
+required, since I'm reasonably sure its impossible to load those
+functions as packed arrays (they are all defined as operators), but lets
+have a belt and braces approach, the additional time cost is negligible.
