Behdad Esfahbod	4b4a1b9f23	Fix assert fail with contextual matching ... As discovered by libFuzzer / Chromium fuzzing. Fixes https://bugs.chromium.org/p/chromium/issues/detail?id=659496 CC https://github.com/behdad/harfbuzz/issues/139	2016-12-21 23:14:16 -06:00
Behdad Esfahbod	c373155904	[fuzzing] Add test for recent fix ... Test from https://github.com/behdad/harfbuzz/issues/223 I forgot that we do run hb-fuzzer on tests in shaping/tests/fuzzed.tests.	2016-02-19 15:13:07 +07:00
Behdad Esfahbod	9cc1ed4fa6	Do not allow recursiving to same position and same lookup ... This is just to make it harder to be extremely slow. There definitely are ways still, just harder. Oh well... how do we tame this problem without solving halting problem?! Fixes https://github.com/behdad/harfbuzz/issues/174	2015-11-19 12:39:09 -08:00
Behdad Esfahbod	85062e3b46	Add tests for previous two commits ... To fully test what these are supposed to test, they should be run against libharfbuzz-fuzzing.la instead of libharfbuzz.la, but for now just record the files.	2015-11-18 23:09:13 -08:00
Behdad Esfahbod	5a7eb5d4d8	[fuzzing] Add test case for OOM ... From https://github.com/behdad/harfbuzz/issues/161	2015-11-06 00:01:24 -08:00

Behdad Esfahbod	df698f3299	[ot-font] Fix hmtx table length checking, *again* ... Exactly the same problem that I fixed in 63ef0b41dc I rewrote the table checking yesterday in 67f8821fb2 and introduced the exact same issue again. :( Good thing we have ongoing fuzzing going now. Was discovered immediately by libFuzzer. Thanks kcc! https://github.com/behdad/harfbuzz/issues/139#issuecomment-153449473 Fixes https://github.com/behdad/harfbuzz/issues/156	2015-11-03 12:15:12 -08:00
Behdad Esfahbod	67f8821fb2	[ot] Make bad-hmtx handling match FreeType ... Also route fuzzing-related tests through hb-ot-font, to reduce dependency on FreeType behavior for badly-broken fonts. Fixes failing test with FreeType master.	2015-11-02 15:37:29 -08:00
