CVE-2016-4389
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 Filter SDK in HPE KeyView 10.18 through 10.24 allows remote attackers to execute arbitrary code via unspecified vectors, a different vulnerability than CVE-2016-4387, CVE-2016-4388, and CVE-2016-4390.
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 confidenceThe vulnerability exists in HPE KeyView's Filter SDK versions 10.18 through 10.24, allowing remote attackers to execute arbitrary code via unspecified vectors. This is a code execution flaw in the document filtering and processing component of KeyView, which is used to parse and extract content from various file formats.

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.
-
Locate HPE KeyView installationSearch for KeyView-related directories, executables, or libraries on the system. Common locations may include /opt/hp/keyview, /usr/local/keyview, or installation directories under the user's home folder. Check for processes named keyview, kvfilter, or related binaries.Affected if HPE KeyView software is found on the system
-
Identify installed KeyView versionLook for version information in installation files, readme files, or version metadata within the KeyView directory. Check for a version file or examine the properties of keyview executables or libraries.Affected if The installed version matches exactly 10.18.0.0, 10.19.0.0, 10.20.0.0, 10.21.0.0, 10.22.0.0, 10.23.0.0, or 10.24.0.0
-
Determine if Filter SDK component is presentExamine the KeyView installation for the presence of filter SDK components, filter libraries, or parsing modules used for document content extraction. Look for directories or files named filter, sdk, or parsers within the KeyView installation.Affected if The Filter SDK component is installed and active within the KeyView environment
-
Check for active KeyView filtering servicesReview running processes or services that utilize KeyView for document parsing. Look for applications or services that invoke KeyView libraries to process file formats.Affected if Any service or application is actively using KeyView to filter or process document files
A system is affected if HPE KeyView Filter SDK versions 10.18.0.0 through 10.24.0.0 are installed and actively processing documents with the filtering component enabled.

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 dataApply the vendor-supplied patch or upgrade to a patched version of HPE KeyView beyond 10.24. If immediate patching is not possible, network segmentation and restricting access to the KeyView service can reduce exposure.
