-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.

-For the rare occasions when the graphics library directly opens a file
-(currently for reading), this allows us to apply any restrictions on
-file access normally applied in the interpteter.

-operator not to validate its parameter(s).

+Subject: [PATCH] Bug 697846: revision to commit 4f83478c88 (.eqproc)
+
+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.

-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.
