    The updated packages fix security vulnerabilities:
    
    A stack-based buffer over-read in the PdfEncryptMD5Base::ComputeEncryptionKey()
    function in PdfEncrypt.cpp in PoDoFo 0.9.6-rc1 could be leveraged by remote 
    attackers to cause a denial-of-service via a crafted pdf file. (CVE-2018-12983)
    
    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. (CVE-2018-20751)
    
    PoDoFo::Impose::PdfTranslator::setSource() in pdftranslator.cpp in PoDoFo 0.9.6
    has a NULL pointer dereference that can (for example) be triggered by sending a
    crafted PDF file to the podofoimpose binary. It allows an attacker to cause
    Denial of Service (Segmentation fault) or possibly have unspecified other impact.
    (CVE-2019-9199)
    
    PoDoFo 0.9.6 has a heap-based buffer overflow in PdfString::ConvertUTF16toUTF8 in
    base/PdfString.cpp. (CVE-2019-9687)
    
    The PoDoFo::PdfVariant::DelayedLoad function in PdfVariant.h in PoDoFo 0.9.6 allows
    remote attackers to cause a denial of service (NULL pointer dereference) via a
    crafted file, because of ImageExtractor.cpp. (CVE-2019-20093)
