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 HP KeyView is installed
    Search the system for HP KeyView components, libraries, or SDK installations. Check common software installation directories, program files, and development tool locations for KeyView-related files or packages.
    Affected if HP KeyView or its Filter SDK component is found on the system
  2. Determine the installed KeyView version
    Locate version information for the HP KeyView installation. Look for version metadata in installed files, product information files, or use vendor-provided version detection methods. Extract the numerical version number.
    Affected if The version number cannot be determined or is not clearly displayed
  3. Compare installed version against affected range
    Take the installed version number and compare it to version 11.2. The affected range is any version earlier than 11.2 (e.g., 11.1, 11.0, 10.x, earlier).
    Affected if The installed version is below 11.2 (e.g., 11.1.x, 10.x, or any earlier release)
  4. Verify the Filter SDK component is in use
    Determine whether the KeyView Filter SDK component is deployed or actively used within the environment. This component handles file format parsing and filtering.
    Affected if The Filter SDK component is present and processing files

The environment is affected if HP KeyView Filter SDK is installed with any version earlier than 11.2.

Upgrade available Upgrade to 11.2 or later
Fixed in 11.2
Interim mitigation

Upgrade HP KeyView to version 11.2 or later to remediate this buffer overflow vulnerability. Given the remote code execution capability, priority remediation is critical.

Recommended fix High confidence

KeyView v11.2 or later

  1. 1. Identify all systems running HP KeyView versions earlier than 11.2
  2. 2. Download KeyView version 11.2 or later from the official HPE support site (support.hpe.com)
  3. 3. Review the HP KeyView 11.2 release notes for any migration or compatibility considerations
