An issue was discovered in PoDoFo 0.9.5. The function PdfDocument::Append() in PdfDocument.cpp in PoDoFo 0.9.5 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted PDF document.

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

  - An issue was discovered in PoDoFo 0.9.5. The function PdfDocument::Append() in PdfDocument.cpp in PoDoFo     0.9.5 allows remote attackers to cause a denial of service (NULL pointer dereference and application     crash) via a crafted PDF document. (CVE-2018-11256)

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:

  - Heap-based buffer overflow in the PdfParser::ReadObjects function in base/PdfParser.cpp in PoDoFo 0.9.5
    allows remote attackers to cause a denial of service (application crash) or possibly have unspecified
    other impact via vectors related to m_offsets.size. (CVE-2017-8378)

  - The PoDoFo::PdfXObject::PdfXObject function in PdfXObject.cpp in PoDoFo 0.9.5 allows remote attackers to
    cause a denial of service (NULL pointer dereference) via a crafted file. (CVE-2017-6848)

  - The PoDoFo::PdfPainter::ExpandTabs function in PdfPainter.cpp in PoDoFo 0.9.5 allows remote attackers to
    cause a denial of service (heap-based buffer over-read and application crash) via a crafted PDF document.
    (CVE-2017-7378)

  - The PoDoFo::PdfSimpleEncoding::ConvertToEncoding function in PdfEncoding.cpp in PoDoFo 0.9.5 allows remote
    attackers to cause a denial of service (heap-based buffer over-read and application crash) via a crafted
    PDF document. (CVE-2017-7379)

  - The doc/PdfPage.cpp:614:20 code in PoDoFo 0.9.5 allows remote attackers to cause a denial of service (NULL
    pointer dereference and application crash) via a crafted PDF document. (CVE-2017-7380)
