CVE-2016-7856
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 · uneditedAdobe DNG Converter versions 9.7 and earlier have an exploitable memory corruption vulnerability. Successful exploitation could lead to arbitrary code execution.
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 confidenceAdobe DNG Converter versions 9.7 and earlier contains a memory corruption vulnerability that can be exploited to achieve arbitrary code execution. The CVSS 9.8 score indicates the exploit is likely remotely triggerable with minimal complexity, potentially through a specially crafted DNG image file.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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.
-
Verify Adobe DNG Converter installationSearch for Adobe DNG Converter in the system program list or file system, typical locations include Program Files or Program Files (x86) folders on WindowsAffected if Adobe DNG Converter is found installed on the system
-
Retrieve installed version numberRight-click the Adobe DNG Converter executable, select Properties, and view the File Version information in the Details tab, or use the command: wmic product where "name like 'Adobe DNG Converter'" get versionAffected if Version cannot be determined or the executable exists without version metadata
-
Compare version to affected rangeCompare the installed version number against the affected range: any version 9.7 or lower is vulnerable. Version 9.7 and earlier should be flagged as potentially affected.Affected if Installed version is 9.7 or any version number lower than 9.7
-
Assess exposure to untrusted DNG filesCheck if the system processes DNG files from untrusted sources, or if users have the ability to open arbitrary DNG files with Adobe DNG Converter. Look for recent .dng files in download folders or shared locations.Affected if Users can open or convert DNG files from untrusted or unknown sources using the installed Adobe DNG Converter
The system is affected if Adobe DNG Converter version 9.7 or earlier is installed AND the application is used to process DNG files, including potentially untrusted ones.

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 dataUpgrade Adobe DNG Converter to a version newer than 9.7, or implement application whitelisting and input validation to block untrusted DNG files from being processed until the update can be applied.
