I don't think it's come through here yet. A buffer overflow flaw was reported in pyfribidi's fribidi_utf8_to_unicode() function, due to it handling at most 3 bytes for a single unicode character. If a 4-byte utf-8 sequence was supplied, it would generate 2 unicode characters which would overflow the logical buffer. This has been fixed in pyfribidi 0.11.
