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.

2016-10-03Fix potentially uninitialized value.chromium/2880dsinclair
Depending on what ReadOK does it's possible for |dircount16| to be used without being initialized. The read code calls back into PDFium specific code which then calls into the stream reading code. Initialize the value to be sure it is set. BUG=chromium:651632 Review-Url: https://codereview.chromium.org/2389993002
