Security readout for executives and security teams

Plain-English summary

CVE-2011-1145 is a possible buffer overflow in unixODBC before 2.2.14p2. It is triggered by an oversized SAVEFILE value in an ODBC connection string. Business risk depends on whether applications use old unixODBC versions and allow connection strings or SAVEFILE values to be influenced by users or external data.

Executive priority

Handle this as legacy dependency risk unless exposure analysis finds untrusted connection-string input. Prioritize remediation on systems running affected unixODBC versions in business-critical applications or environments where users can influence database connection parameters.

Technical view

The issue is in SQLDriverConnect() in unixODBC before 2.2.14p2. The source bundle describes a possible buffer overflow when a large SAVEFILE parameter is supplied in the connection string. No CVSS, CWE, confirmed impact, or exploit details are provided in the bundle.

Likely exposure

Exposure is most likely on legacy Linux or Unix systems running unixODBC before 2.2.14p2, especially where applications dynamically build ODBC connection strings. Exposure is lower where connection strings are static, access-controlled, and not influenced by untrusted input.

Exploitation context

The provided bundle does not show CISA KEV listing or active exploitation evidence. It only supports that a large SAVEFILE connection-string value may trigger a buffer overflow condition. Practical exploitability and impact are not established by the supplied sources.

Researcher notes

Evidence is sparse: no CVSS, CWE, exploit status, or detailed impact is present in the supplied bundle. The version boundary before 2.2.14p2 is clear, but validation should focus on real package versions and whether the vulnerable code path is reachable.

Mitigation direction

  • Inventory systems and applications using unixODBC.
  • Upgrade unixODBC to 2.2.14p2 or a vendor-fixed package.
  • Check Debian, Red Hat, and SUSE guidance for package-specific status.
  • Restrict who can modify ODBC connection strings or SAVEFILE values.
  • Treat externally supplied connection-string data as unsafe input.

Validation and detection

  • Confirm installed unixODBC package versions across managed hosts.
  • Identify applications that call SQLDriverConnect() through unixODBC.
  • Review whether SAVEFILE or connection strings accept untrusted input.
  • Verify vendor advisory status for each distribution package.
  • Regression test ODBC connection workflows after updating packages.
