-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.
