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.

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

  - 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)

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 Fedora 29 host has packages installed that are affected by multiple vulnerabilities as referenced in the FEDORA-2018-6b9320d9c9 advisory.

    This update fixes multiple security vulnerabilities:  CVE-2018-5783, CVE-2018-11254, CVE-2018-11255,     CVE-2018-11256, CVE-2018-12982, CVE-2018-14320, CVE-2018-19532



Tenable has extracted the preceding description block directly from the Fedora security advisory.

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