Name of the Vulnerable Software and Affected Versions Oracle MySQL Server versions 5.5.59 and prior Oracle MySQL Server versions 5.6.39 and prior Oracle MySQL Server versions 5.7.21 and prior
Description The issue is related to insufficient access control in the Server: Locking component of Oracle MySQL Server, allowing a remote attacker to cause a denial of service via the MySQL protocol.

Recommendations For Oracle MySQL Server versions 5.5.59 and prior, update to a version later than 5.5.59 to resolve the issue.
