2017-03-13LibopenJPEG: Fix some divisions by 0 in pi.cNicolas Pena
The undefined shifts in libopenjpeg are sometimes used as divisors. This CL checks that we are not trying to divide by 0 or mod by 0 in some places in pi.c.

2017-03-01LibOpenJPEG upstream: check size in opj_j2k_read_sizNicolas Pena
This happens to fix the bug in question but I suspect they still do not have enough checks to prevent undefined shifts.

2017-01-25Use opj_uint_ceildiv where it is better than its int versionNicolas Pena
Replaced (OPJ_UINT32)opj_int_ceildiv((OPJ_INT32)a, (OPJ_INT32) b) with opj_uint_ceildiv(a, b), which makes much more sense.

2017-01-24Check m_data!=null when adding mctNicolas Pena
m_decorrelation_array and m_offset_array can be assigned to l_mct_data, which can be set in opj_j2k_read_mct. In this method, there can be an early true return before allocating m_data but after freeing it.

If we do not do this check, it will overflow to a huge unsigned int, so we will allocate a lot of memory etc. BUG=682182 Change-Id: I24b6654860c43e5d4deea753868b9d842f859cff Reviewed-on: https://pdfium-review.googlesource.com/2272 Reviewed-by: dsinclair <dsinclair@chromium.org> Reviewed-by: Tom Sepez <tsepez@chromium.org> Commit-Queue: Nicolás Peña <npm@chromium.org>
2017-01-10Fix m_nb_mct_records calculation in opj_j2k_read_mctNicolas Pena
Now we update m_nb_mct_records only when there was a new mct record, and l_mct_data computations all went through. In previous version, the ++l_tcp->m_nb_mcc_records was in the end, without the if. Notice that this is similar to the analoguous in opj_j2k_read_mcc.

2016-03-18openjpeg: Remove unneeded non-standard code.Nico Weber
When building with clang-cl and not passing /FIintrin.h, the __attribute__ defined to nothing, which confuses the compiler (see bug). Since nothing seems to require the __attribute__ redefinition, just remove it.

2016-03-10openjpeg: Don't build with SSE instrinsics for 32-bit x86.Oliver Chang
Fixes 32-bit clang-cl build. These intrinsics require addresses with 16-byte alignment, which doesn't cause issues for 64-bit builds because of allocator alignment. MSVC doesn't recognise the __SSE__, __SSE2__ defines, which is why this problem never surfaced before. R=tsepez@chromium.org BUG=pdfium:433 Review URL: https://codereview.chromium.org/1783813003 .
