Because the name length is not bounded before the driver builds its diagnostic message, memory adjacent to that buffer is overwritten with user-supplied content. This can terminate the hosting application process and may allow unintended code to run within it.\n\n## Affected\n\n- `bi_connector_odbc_driver < 1.4.10`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `bi_connector_odbc_driver 1.4.10`","depth":"twilight","depthScore":48,"depthScoreParts":{"impact":48.4,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
