Description Dhananjay Arunesh 2019-02-05 13:30:30 UTC 
An issue was discovered in crop_page in PoDoFo 0.9.6. For a crafted PDF document, pPage->GetObject()->GetDictionary().AddKey(PdfName("MediaBox"),var) can be problematic due to the function GetObject() being called for the pPage NULL pointer object. The value of pPage at this point is 0x0, which causes a NULL pointer dereference.
