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 · unedited
Stack-based buffer overflow in IBM Tivoli Storage Manager FastBack 5.5 and 6.1.x through 6.1.11.1 allows remote attackers to cause a denial of service (daemon crash) via unspecified vectors, a different vulnerability than CVE-2016-0212 and CVE-2016-0213.

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 confidence

Stack-based buffer overflow vulnerability in IBM Tivoli Storage Manager FastBack versions 5.5 and 6.1.x through 6.1.11.1 allows remote attackers to crash the FastBack daemon via unspecified vectors. The critical CVSS score of 9.8 indicates severe potential impact, though the official description focuses on denial of service.

MitigationApply the applicable IBM fix pack for Tivoli Storage Manager FastBack to address this vulnerability. If immediate patching is not possible, restrict network access to the FastBack service and monitor for anomalous activity.

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. Verify IBM Tivoli Storage Manager FastBack is installed
    On Windows, check Programs and Features or the Windows registry for IBM Tivoli Storage Manager FastBack. On Linux, check for RPM packages with 'rpm -qa | grep -i fastback' or inspect /opt directory for FastBack installation folders.
    Affected if FastBack software is found on the system
  2. Identify the installed FastBack version number
    On Windows, locate the FastBack version via the About section in the FastBack GUI or check the registry under the FastBack installation key. On Linux, run 'rpm -qi' on the identified FastBack package or check version files in the installation directory.
    Affected if A version number is returned that matches the installed FastBack software
  3. Compare installed version against affected ranges
    Compare the identified version to the affected list: 5.5.0, 6.1.0, 6.1.0.1, 6.1.1, 6.1.1.0, 6.1.2, 6.1.2.0, 6.1.3, 6.1.3.0, 6.1.4, 6.1.4.0, or 6.1.5
    Affected if The installed version is exactly 5.5.0 or falls within the 6.1.x range up to and including 6.1.5
  4. Confirm the FastBack daemon service is exposed
    Check network configuration to determine if the FastBack server listens on accessible network ports (default ports 11460 or similar) and whether those ports are reachable from network segments outside the trusted environment.
    Affected if The FastBack service is network-accessible and the version is within the affected range

The system is affected if IBM Tivoli Storage Manager FastBack version 5.5.0 or any 6.1.x version through 6.1.5 is installed and the service is network-accessible.

Recommended fix Moderate confidence

Tivoli Storage Manager FastBack version 6.1.12 or later (or latest available supported release)

  1. 1. Identify the current installed version of IBM Tivoli Storage Manager FastBack by checking the server or using the administrative console.
  2. 2. Determine the appropriate upgrade path based on your current version - plan for either a major version jump or sequential updates.
  3. 3. Review IBM's official support lifecycle for Tivoli Storage Manager FastBack to identify the recommended fixed release.
  4. 4. Download the fixed version from IBM Fix Central (https://www-945.ibm.com/support/fixcentral/) or your authorized IBM distribution channel.
  5. 5. Before applying the upgrade, perform a complete backup of the TSM FastBack server configuration, database, and any critical data.
  6. 6. Schedule a maintenance window as upgrades may require service downtime.
  7. 7. Stop the TSM FastBack services following the documented procedure for your version.
  8. 8. Install the upgraded version following IBM's installation documentation for the target release.
Caveat Upgrading TSM FastBack may require configuration migration; review IBM migration guides. Test thoroughly in a non-production environment before deploying to production.
