Heap corruption in j2k encoder #5

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
(OpenJPEG 1.3, Vista Business)

On some gray16 images (conceivably which have too many different colors)
j2k encoder crashes while freeing memory in tcd_free_encode(opj_tcd_t *tcd)
on this string:
   opj_free(prc->cblks.enc[cblkno].data - 2);

dbgheap.c
> image_to_j2k.exe!_CrtIsValidHeapPointer(const void *
pUserData=0x01069f20)

Version 1.2 didn't crash on such images, but i tested it less than 1.3,
since i need lossless j2k.

Steps to reproduce: try to encode attached file (random.tif) with
image_to_j2k.exe

Indeed, the memory allocated for prc->cblks.enc[cblkno].data is too small for 
16 bit 
depth components. I'm working on this one.
