High
Published: Translated: NVD NIST

Summary

A race condition vulnerability exists in Oracle MySQL, MariaDB, Percona Server, and Percona XtraDB Cluster that allows local users with certain permissions to gain elevated privileges. The issue involves the use of my_copystat during REPAIR TABLE on a MyISAM table.

Risk Assessment

Organizations may be exposed to unauthorized access to data and resources, potentially leading to serious security breaches. The elevation of privileges for local users could result in unauthorized access to critical systems.

Recommendation

It is recommended to upgrade to the latest versions of MySQL, MariaDB, Percona Server, and Percona XtraDB Cluster to mitigate this vulnerability. Additionally, local user permissions should be restricted to the minimum necessary.
