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.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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)

Note that Nessus relies on the presence of the package as reported by the vendor.

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - PoDoFo 0.9.6 has a heap-based buffer overflow in PdfString::ConvertUTF16toUTF8 in base/PdfString.cpp.
    (CVE-2019-9687)

  - A NULL pointer dereference vulnerability exists in the function PdfTranslator::setTarget() in
    pdftranslator.cpp of PoDoFo 0.9.6, while creating the PdfXObject, as demonstrated by podofoimpose. It
    allows an attacker to cause Denial of Service. (CVE-2018-19532)

  - 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)

  - An issue was discovered in PoDoFo 0.9.6. There is an attempted excessive memory allocation in
    PoDoFo::podofo_calloc in base/PdfMemoryManagement.cpp when called from
    PoDoFo::PdfPredictorDecoder::PdfPredictorDecoder in base/PdfFiltersPrivate.cpp. (CVE-2018-20797)

  - 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)

The remote openSUSE 15 host has packages installed that are affected by a vulnerability as referenced in the SUSE- SU-2022:1316-1 advisory.

  - 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)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote SUSE Linux SLED12 / SLED_SAP12 / SLES12 / SLES_SAP12 host has packages installed that are affected by a vulnerability as referenced in the SUSE-SU-2022:1690-1 advisory.

  - 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)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

This update fixes CVE-2019-20093.
