kdu_expand -i ../../data/issue399/0.jp2 -o 0.bmp
Kakadu Core Error:
Illegal inclusion tag tree encountered while decoding a packet header.  This
problem can arise if empty packets are used (i.e., packets whose first header
bit is 0) and the value coded by the inclusion tag tree in a subsequent packet
is not exactly equal to the index of the quality layer in which each code-block
makes its first contribution.  Such an error may arise from a
mis-interpretation of the standard.  The problem may also occur as a result of
a corrupted code-stream.  Try re-opening the image with the resilient mode
enabled.

This patch resets "resno_decoded" in tcd_init_tile.
Main COD marker has numlevels==5
Tile COD marker for tile 5 (4 zero based, but output has changed since) has numlevels==1

Trying to decode dwt for the tile with too much levels.

Feel free to correct the place where this shall be reset.

The patch has passed all tests & is OK (no regressions)
Renamed image to 0.j2k
The output image is not the same as Kakadu for tile 6 (5 zero based). This is probably
related to Kakadu warning.

@antonin,

Yes, it's been verified against the whole Test Suite.

Status changed: Verified

gcode-importer · 2014-10-22T13:14:58Z

Thanks. 
I'll close this issue and create a new (public) one with the very same image as a warning
should at least be issued (as in kakadu behaviour): the center of the image is corrupted
and we should inform the user about that.

Hi Antonin, when reviewing code with chromium security team, they raise a question about
the fix here:

Line 1063 of tcd.c: memset(p_code_block, 0, sizeof(opj_tcd_cblk_dec_t));

How do we know that p_code_block can accomodate sizeof(...) bytes?  Is there an
early check against, say, p_code_block->data_max_size?

Can you also cc tsepez@chromium.org in this and future security issues? Thanks!

@bo_xu,

Allocation of code blocks is done from line 900. When opj_tcd_code_block_dec_allocate
is called (line 973), it can be easily reviewed that p_code_block points to a memory
block of at least sizeof(opj_tcd_cblk_dec_t).

p_code_block->data_max_size relates to the size of allocated memory for p_code_block->data
& not p_code_block. 

All is ok here.
