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 UniVerse with UV/ODBC allows attackers to cause a denial of service (client crash or server CPU consumption) via a query with an invalid link between tables, possibly via a buffer overflow.

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

IBM UniVerse UV/ODBC driver contains a vulnerability where malformed SQL queries containing invalid links between tables can trigger either client crashes or excessive server CPU consumption, potentially due to a buffer overflow condition in the ODBC driver when processing malformed table join queries.

MitigationApply IBM UniVerse patches or updates to address this vulnerability. If no patches are available, consider restricting ODBC access to trusted clients and implementing query validation or timeout mechanisms to mitigate DoS conditions.

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 IBM UniVerse installation
    Search for IBM UniVerse or U2 Universe installation directories or check system for installed software named 'UniVerse' or 'U2 Universe'
    Affected if IBM UniVerse or U2 Universe software is found on the system
  2. Locate the UV/ODBC driver files
    Search for ODBC driver files associated with UniVerse, such as uvodbc.dll or similar ODBC driver libraries in the UniVerse installation directory or system driver folders
    Affected if UV/ODBC driver files are present on the system
  3. Check for configured ODBC data sources
    Review Windows ODBC Data Source Administrator (ODBCAD32.exe) or Unix ODBC configuration files for data sources using the UniVerse ODBC driver
    Affected if Any ODBC data sources are configured to connect to UniVerse databases
  4. Verify ODBC connectivity is enabled
    Confirm the ODBC driver is registered and accessible by attempting to enumerate ODBC drivers or checking driver manager configuration
    Affected if The UniVerse ODBC driver is registered and available for connections
  5. Review ODBC driver version
    If the driver is present, identify its version through driver properties or file version information and compare against any available patch information
    Affected if The ODBC driver version cannot be determined or is unpatched

The environment is affected if IBM UniVerse with the UV/ODBC driver is installed and ODBC data sources are configured, since all versions of this product are vulnerable to malformed SQL query handling issues.
