From 5d499272b95a6b890a1397e11d20937de000d31b Mon Sep 17 00:00:00 2001
From: Ray Johnston <ray.johnston@artifex.com>

Subject: [PATCH] Bug 702582, CVE 2020-15900 Memory Corruption in Ghostscript
9.52
Fix the 'rsearch' calculation for the 'post' size to give the correct
size. Previous calculation would result in a size that was too large,
and could underflow to max uint32_t. Also fix 'rsearch' to return the
correct 'pre' string with empty string match.
A future change may 'undefine' this undocumented, non-standard operator
during initialization as we do with the many other non-standard internal
PostScript operators and procedures.
