-       tests: avoid a spurious failure on older debian
+      tests: avoid false ulimit failure on some systems
+
+      * tests/misc/cut-huge-range.sh: On some systems returns_ may
+      use more memory, so incorporate that in the determination
+      of the ulimit value to use.  Noticed on ARMv7 with bash-4.4.12,
+      and x86_64 with bash-4.2.37.
+      Fixes http://bugs.gnu.org/26253
 
 ... which appeared to be insufficient.

-Subject: [PATCH] [psaux] Better protect `flex' handling.
-
-Reported as
-
-  https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=935
-
-* src/psaux/t1decode.c (t1_decoder_parse_charstrings)
-<callothersubr>: Since there is not a single flex operator but a
-series of subroutine calls, malformed fonts can call arbitrary other
-operators after the start of a flex, possibly adding points.  For
-this reason we have to check the available number of points before
-inserting a point.

-Subject: [PATCH] DSC parser - validate parameters
-
-Bug #697190 ".initialize_dsc_parser doesn't validate the parameter is a dict type before using it."
-
-Regardless of any security implications, its simply wrong for a PostScript
-operator not to validate its parameter(s).
-
-No differences expected.

+When using the "DELAYBIND" feature, it turns out that .eqproc can be called with
+parameters that are not both procedures. In this case, it turns out, the
+expectation is for the operator to return 'false', rather than throw an error.

+This patch makes the UUIDs in the XMP header optional, depending on the
+setting of the environment variable GS_GENERATE_UUIDS.
+
+If the environment variable GS_GENERATE_UUIDS is set to "0" or "no", it will
+not write out the Document UUID field and also will write the Instance ID
+field value as "".
+
+Upstream does not want to do this.

-Subject: [PATCH] asn1_find_node: added safety check on asn1_find_node()
-
-This prevents a stack overflow in asn1_find_node() which
-is triggered by too long variable names in the definitions
-files. That means that applications have to deliberately
-pass a too long 'name' constant to asn1_write_value()
-and friends.  Reported by Jakub Jirasek.

-
-2016-12-03 Even Rouault <even.rouault at spatialys.com>
-
-        * libtiff/tif_dirread.c: modify ChopUpSingleUncompressedStrip() to
-        instanciate compute ntrips as TIFFhowmany_32(td->td_imagelength,
-rowsperstrip),
-        instead of a logic based on the total size of data. Which is faulty is
-        the total size of data is not sufficient to fill the whole image, and
-thus
-        results in reading outside of the StripByCounts/StripOffsets arrays
-when
-        using TIFFReadScanline().
-        Reported by Agostino Sarubbo.
-        Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2608.
-
-        * libtiff/tif_strip.c: revert the change in TIFFNumberOfStrips() done
-        for http://bugzilla.maptools.org/show_bug.cgi?id=2587 / CVE-2016-9273

-Subject: [PATCH] util/disk_cache: fix size subtraction on 32bit
-
-Negating size_t on 32bit produces a 32bit result. This was effectively
-adding values close to UINT_MAX to the cache size (the files are usually
-small) instead of intended subtraction.
-Fixes 'make check' disk_cache failures on 32bit.
