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
IBM Concert Software 1.0.0 through 1.1.0 could allow a remote attacker to obtain sensitive information from allocated memory due to improper clearing of heap memory.

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

IBM Concert Software versions 1.0.0 through 1.1.0 contains a heap memory disclosure vulnerability where allocated memory containing sensitive data is not properly cleared before being freed or reused. A remote attacker could potentially read residual sensitive information from heap memory that was not zeroed out after use, leading to information disclosure.

MitigationApply vendor patches when available. In the interim, ensure proper secure coding practices are followed: explicitly zero out sensitive data in heap memory before freeing (using functions like memset or explicit_bzero), and conduct memory forensic review of heap allocations containing sensitive data.

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 IBM Concert is installed
    Check for IBM Concert installation by looking for the 'concert' binary or service. Common locations: /opt/ibm/concert, /usr/local/concert, or check system packages with 'rpm -qa | grep -i concert' (RHEL) or 'dpkg -l | grep -i concert' (Debian).
    Affected if IBM Concert software is found on the system
  2. Determine the installed version
    Run 'concert --version' or 'concert version' if the binary is available. If installed via package manager, use 'rpm -qi <package-name>' or 'dpkg -s <package-name>' to retrieve version information.
    Affected if Version is 1.0.0 through 1.1.0 (inclusive)
  3. Verify version is in affected range
    Compare the installed version number against the affected range: >= 1.0.0 and < 2.0.0. If the version starts with '1.0.' or '1.1.' it is likely within the affected range.
    Affected if Version begins with 1.0.x or 1.1.x, indicating it is between 1.0.0 and 1.1.0
  4. Check if IBM Concert service is running
    Check service status with 'systemctl status concert' or 'service concert status' depending on the init system. Also check for listening ports commonly used by Concert with 'netstat -tlnp | grep concert' or 'ss -tlnp | grep concert'.
    Affected if Service is actively running and exposing network interfaces

You are affected if IBM Concert version 1.0.0 through 1.1.0 is installed and the service is running, as the vulnerability allows reading residual sensitive data from heap memory.

Upgrade available Upgrade to 2.0.0 or later
Fixed in 2.0.0
Interim mitigation

Apply vendor patches when available. In the interim, ensure proper secure coding practices are followed: explicitly zero out sensitive data in heap memory before freeing (using functions like memset or explicit_bzero), and conduct memory forensic review of heap allocations containing sensitive data.

Recommended fix Moderate confidence

IBM Concert 2.0.0 or later

  1. 1. Review IBM Concert Software 2.0.0 release notes and migration documentation
  2. 2. Back up current IBM Concert configuration and data
  3. 3. Test upgrade in a non-production environment to verify compatibility
  4. 4. Schedule maintenance window for production upgrade
  5. 5. Upgrade IBM Concert to version 2.0.0 or later following official upgrade procedures
  6. 6. Verify the upgrade was successful and all services are running
  7. 7. Validate that the vulnerability is resolved
Caveat Upgrading from 1.x to 2.x is a major version change and may introduce breaking changes; review migration guide and test thoroughly before production deployment
