CVE-2016-4403
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 · uneditedA security vulnerability was identified in the Filter SDK component of HP KeyView earlier than v11.2. The vulnerability could be exploited remotely to allow code execution via memory corruption.
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 confidenceA memory corruption vulnerability in the HP KeyView Filter SDK component allows remote attackers to execute arbitrary code by exploiting the memory corruption flaw. This affects versions prior to v11.2, and the vulnerability can be triggered through processing of malicious files or data streams handled by the Filter SDK.

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 HP KeyView is installedSearch for HP KeyView installations on the system. Check common installation directories such as C:\Program Files\HP\KeyView or /opt/hp/keyview. Use system inventory tools or package managers to list installed HP software.Affected if HP KeyView is found installed on the system
-
Determine the installed HP KeyView versionLocate the KeyView version information. Check the main executable or DLL properties, or run 'keyview -v' if a command-line tool exists. Look for version metadata in the installation directory or Windows registry under HKLM\Software\HP\KeyView.Affected if The installed version is lower than 11.2 or the version cannot be determined (treat as vulnerable)
-
Verify the Filter SDK component presenceCheck for the presence of the Filter SDK libraries or modules within the KeyView installation directory. Look for files with names containing 'filter' or 'filt' in the SDK directories.Affected if The Filter SDK component is present in the installation
-
Determine if untrusted file processing occursReview system configurations, logs, or applications that integrate KeyView to determine if the system processes files from untrusted or external sources through the Filter SDK.Affected if The system processes files or data streams from untrusted sources via KeyView Filter SDK
The environment is affected if HP KeyView with a version lower than 11.2 is installed and the Filter SDK component is being used to process files or data streams.

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.
dbcve · scoped11.2
Upgrade HP KeyView to version 11.2 or later to obtain the patched Filter SDK component. If immediate patching is not possible, restrict network access to systems using KeyView and implement input validation on files processed by the SDK.
v11.2
- Upgrade HP KeyView to version 11.2 or later to remediate the memory corruption vulnerability in the Filter SDK component
