CVE-2017-7381
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 · uneditedThe doc/PdfPage.cpp:609:23 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 · high confidenceA NULL pointer dereference vulnerability exists in PoDoFo library version 0.9.5 at doc/PdfPage.cpp:609:23. When processing a specially crafted PDF document, the application attempts to dereference a NULL pointer, causing a denial of service via application crash.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify if PoDoFo library is presentSearch for the PoDoFo library files on the system. On Linux/Unix, use 'find /usr -name "*podofo*" 2>/dev/null' or check package manager listings. On Windows, search for podofo DLL files in application directories.Affected if PoDoFo library files are found on the system
-
Determine the installed PoDoFo versionRun 'pkg-config --modversion podofo' on Linux, or check the version information of the podofo DLL file using 'strings' or file properties. Check application dependency manifests that may list PoDoFo version.Affected if The installed version is exactly 0.9.5
-
Identify applications using PoDoFo for PDF processingReview application dependencies and libraries. Search application binaries for linkage to libpodofo using 'ldd' on Linux or dependency walkers on Windows. Check application documentation for PDF processing capabilities.Affected if An application links against PoDoFo and processes PDF files
-
Check if PDF processing accepts external inputReview application configuration and behavior to determine if it processes PDF documents from external or untrusted sources, such as user uploads, network input, or file imports.Affected if The application processes PDF files from external or untrusted sources
The environment is affected if PoDoFo version 0.9.5 is installed AND an application using this library processes PDF documents from potentially untrusted sources.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate PoDoFo library to a patched version that addresses the NULL pointer dereference. If immediate patching is not possible, implement input validation to reject malformed PDF files before processing.
