-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.
