The PoDoFo::PdfColorGray::~PdfColorGray function in PdfColor.cpp in PoDoFo 0.9.4 allows remote attackers to cause a denial of service (NULL pointer dereference) via a crafted file.

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

  - The PoDoFo::PdfColorGray::~PdfColorGray function in PdfColor.cpp in PoDoFo 0.9.4 allows remote attackers     to cause a denial of service (NULL pointer dereference) via a crafted file. (CVE-2017-6849)

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