Name of the Vulnerable Software and Affected Versions
MySQL Server versions 5.7.36 and prior
MySQL Server versions 8.0.27 and prior
Description
The issue is related to errors in resource release in the MySQL Server product, specifically in the Server: Parser component. It allows a high-privileged attacker with network access via multiple protocols to compromise the MySQL Server. Successful attacks can result in the unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of the MySQL Server.
Recommendations
For MySQL Server versions 5.7.36 and prior, update to a version later than 5.7.36 to resolve the issue.
For MySQL Server versions 8.0.27 and prior, update to a version later than 8.0.27 to resolve the issue.
As a temporary workaround, consider restricting network access to the MySQL Server to minimize the risk of exploitation.
