annotate src/os/win32/ngx_process_cycle.c @ 9322:d6f75dd66761 default tip
Mp4: added and updated sanity checks for "end" handling.
When handling incorrect data in ngx_http_mp4_crop_stsc_data(),
trak->end_chunk_samples might end up being arbitrary large, leading
to reading before the buffer in ngx_http_mp4_update_stsz_atom(). Fix
is to check that trak->end_chunk_samples corresponds to a memory within
the stsz atom data. For consistency, trak->start_chunk_samples
is checked similarly.
Similarly, trak->end_chunk might end up being smaller than trak->start_chunk,
leading to reading memory after the buffer in ngx_http_mp4_update_stco_atom()
and ngx_http_mp4_update_co64_atom(). Corresponding checks are updated
to explicitly test (trak->end_chunk - trak->start_chunk) instead of just
checking trak->end_chunk and assuming it is larger than trak->start_chunk.
This is generally in line with existing checks of
(trak->end_sample - trak->start_sample) in ngx_http_mp4_update_stsz_atom(),
where trak->end_sample might also become smaller than trak->start_sample
when handling incorrect data in ngx_http_mp4_crop_stts_data().
