Description
The vulnerability in the MySQL Server component of Oracle MySQL, specifically in the Server:Optimizer subcomponent, is related to inadequate access control. This issue can be exploited by a remote attacker to cause a denial of service via the MySQL network protocol. Successful attacks can result in the ability to cause a hang or frequently repeatable crash of the MySQL Server.
