2017-07-20LibTIFF: remove a couple of patchesNicolas Pena
This CL removes two patches that correspond to non-security CF bugs. There are now only a few patches left: two patches to prevent overflow in _TIFFCheckRealloc (overflows here are dangerous as they can cause heap-buffer-overflows), one patch to prevent integer overflows which CF reported as a security issue, and one recent upstream patch (which would be removed in the next LibTIFF upgrade). Next steps: * Figure out how to reproduce the security issue from _TIFFCheckRealloc (samples from the bugs seem to just timeout on asan) and report bug upstream once it's confirmed that a change is needed. * Ditto integer overflow, except it was already reported upstream, so ping upstream once reproduction without the patch is possible again.

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.
