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 the FastBackMount process in IBM Tivoli Storage Manager FastBack 6.1 before 6.1.11.1 allows remote attackers to execute arbitrary code via unspecified vectors.

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 · high confidence

A stack-based buffer overflow exists in the FastBackMount process of IBM Tivoli Storage Manager FastBack version 6.1 before 6.1.11.1. The vulnerability allows remote attackers to execute arbitrary code via unspecified vectors, likely through malformed input to the FastBackMount service.

MitigationApply IBM Tivoli Storage Manager FastBack version 6.1.11.1 or later to address the buffer overflow. If immediate patching is not feasible, restrict network access to the FastBackMount service and monitor for indicators of compromise.

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
    Locate the FastBack installation directory, typically under C:\Program Files\IBM\Tivoli\TSM\FastBack or /opt/IBM/Tivoli/TSM/FastBack on Unix systems. Check for the FastBack software and its components.
    Affected if The software is present on the system
  2. Determine the installed FastBack version
    Check the version of the FastBack installation. On Windows, inspect the version information of the FastBack executables or check the product details in the registry under HKLM\SOFTWARE\IBM\Tivoli\Storage Manager\FastBack. On Unix, run the appropriate version query command or inspect version files in the installation directory.
    Affected if The installed version matches any of: 6.1.0.1, 6.1.1.0, 6.1.7.2, 6.1.8.0, 6.1.8.1, 6.1.9.0, 6.1.9.1, 6.1.10.0, 6.1.10.1, or 6.1.11.0, or is any version below 6.1.11.1
  3. Confirm the FastBackMount service is running
    On Windows, open Services and look for a service named FastBackMount or similar. On Unix, check running processes for fastbmnt or fastmount daemons. Use commands like 'sc query' on Windows or 'ps -ef | grep -i fastb' on Unix.
    Affected if The FastBackMount process or service is active on the system
  4. Assess network exposure of the FastBackMount service
    Check which network ports the FastBackMount service is listening on. Use netstat or equivalent tools to identify ports associated with the FastBackMount process. Review firewall rules and network configuration to determine if the service is exposed to untrusted networks.
    Affected if The FastBackMount service is accessible over the network to untrusted parties

A system is affected if IBM Tivoli Storage Manager FastBack version 6.1.0.1 through 6.1.11.0 is installed with the FastBackMount process running and potentially exposed to network access.

Interim mitigation

Apply IBM Tivoli Storage Manager FastBack version 6.1.11.1 or later to address the buffer overflow. If immediate patching is not feasible, restrict network access to the FastBackMount service and monitor for indicators of compromise.

Recommended fix High confidence

6.1.11.1 or later

  1. 1. Identify the current IBM Tivoli Storage Manager FastBack version by running: dsmc query session or checking the FastBackMount service version
  2. 2. Download IBM Tivoli Storage Manager FastBack version 6.1.11.1 or later from the IBM Support Portal: http://www-01.ibm.com/support/docview.wss?uid=swg21700536
  3. 3. Stop all FastBack services (FastBackMount, FastBackServer, and related components) before applying the upgrade
  4. 4. Apply the 6.1.11.1 update following IBM's installation instructions in the provided support document
  5. 5. Verify the upgrade was successful by checking the FastBackMount process version matches 6.1.11.1 or later
  6. 6. Restart all FastBack services and verify normal operation
