Remediation
Red Hat statement
This Moderate severity flaw in `mysql-connector-odbc` allows an unauthenticated attacker with local logon access to the system to cause a complete denial of service and gain unauthorized read access to a subset of data. The local attack vector limits the immediate remote exploitability, but successful exploitation can significantly impact system availability and data confidentiality.
Red Hat mitigation
Since this vulnerability requires local logon access, ensure that only trusted users have interactive access to systems running `mysql-connector-odbc`. If the `mysql-connector-odbc` package is not actively used, consider removing it to eliminate the attack surface.
