2017-01-18Bad indexing in CPDF_Document::FindPageIndex when page tree corrupt.tsepez
Moving to std::vector from the more forgiving CFX_ArrayTemplate revealed the dubious page tree traversal, which depends on the correctness of the /Count entries to properly summarize the total descendants under a given node. The only "correct" thing to do is to throw away these counts as parsed, and re-compute them, perhaps in CountPages(). But I'm not willing to do that since it may break unknown documents in the wild.

2017-01-03Force stop of page tree traversal when max level reachedNicolas Pena
The previous implementation, FindPDFPage, was already doing this since the recursive call was always with return. Currently, we were trying to keep going even after reaching max level. The problem is that if the page tree is not a tree, we might loop forever. This could also be solved by keeping track of the dictionaries that have been visited, but this solution takes much less space.
