Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
The PdfFontFactory.cpp:200:88 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.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

A NULL pointer dereference vulnerability exists in PoDoFo 0.9.5's PdfFontFactory.cpp at line 200. When processing a crafted PDF document with malformed font data, the application attempts to dereference a NULL pointer, causing a crash and denial of service.

MitigationImplement proper NULL pointer validation in PdfFontFactory.cpp before dereferencing font-related pointers. Users should avoid opening untrusted PDF documents with PoDoFo-based applications until a patch is applied.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify if PoDoFo is installed
    Run 'podofo-version' or check package manager for podofo package, or inspect application binaries linked against libpodofo
    Affected if PoDoFo library or any application using it is present on the system
  2. Determine the installed PoDoFo version
    Execute version command or check library version via 'ldd' on linked binaries, or check package version
    Affected if Version is exactly 0.9.5
  3. Locate PdfFontFactory source file
    Search for PdfFontFactory.cpp in the source code or installed development headers
    Affected if PdfFontFactory.cpp exists in the build at line 200 vicinity (font handling code)
  4. Verify font processing is used
    Check if the PoDoFo-based application or workflow processes PDF documents, particularly those from untrusted sources
    Affected if The application parses PDF documents containing font definitions

A system is affected if it runs PoDoFo version 0.9.5 and processes PDF documents from untrusted or potentially malicious sources.

Mitigation

Implement proper NULL pointer validation in PdfFontFactory.cpp before dereferencing font-related pointers. Users should avoid opening untrusted PDF documents with PoDoFo-based applications until a patch is applied.
