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.
