commit: https://git.buildroot.net/buildroot/commit/?id=8db0d3901d74ab572ed6013fbbc5ca73c2955cb1
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2019.02.x

Fixes CVE-2019-3835, CVE-2019-3838: A specially crafted PostScript file
could use these flaws to have access to the file system outside of the
constrains imposed by -dSAFER.

Drop upstream patches.

Use the make subst function to compute the download site from version.

-Subject: [PATCH] Sanitize op stack for error conditions
-
-We save the stacks to an array and store the array for the error handler to
-access.
-
-For SAFER, we traverse the array, and deep copy any op arrays (procedures). As
-we make these copies, we check for operators that do *not* exist in systemdict,
-when we find one, we replace the operator with a name object (of the form
-"/--opname--").

-success 0 or <0 on failure. The logic for this case was wrong.

-From: Chris Liddell <chris.liddell at artifex.com>
-Date: Fri, 11 Jan 2019 13:36:36 +0000
-Subject: [PATCH] Remove .forcedef, and harden .force* ops more
-
-Remove .forcedef and replace all uses with a direct call to .forceput instead.
-
-Ensure every procedure (named and trasient) that calls .forceput is
-executeonly.
