CVE-2018-20751

Name
CVE-2018-20751
Description
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.
