2017-03-29Do more checks before big allocs in TIFFReadDirEntryArrayNicolas Pena
This CL fixes the only caller to TIFFReadDirEntryData with potentially large size so that we avoid big mallocs when we know we will fail. It does this as follows: - Avoid the unnecessary computations if datasize is very small. We don't want to be slower in this case. - If !isMapped(tif), we will Seek and Read. Check that ending position is reachable. In the other case, do a simple check for out of bounds.

2017-01-11Really fix m_nb_mct_records calculation in opj_j2k_read_mctNicolas Pena
My previous attempt did not follow precisely the way m_nb_mcc_records is increased in opj_j2k_read_mcc.

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.

2017-01-09[libtiff] Validate refblackwhite valuesDan Sinclair
The td_refblackwhite value is currently assigned without validation. This may pose an issue as the image can specify the value as nan. This will cause problems later when we use the nan in calcluations. This CL validates each of the float values are not nan and if they are sets them to the default provided by the TIFF spec v6.
