Name of the Vulnerable Software and Affected Versions
MySQL Server versions 5.7.28 and prior
MySQL Server versions 8.0.18 and prior
Description
A vulnerability in the MySQL Server product allows a highly privileged attacker with network access via multiple protocols to compromise the server. Successful attacks can result in the unauthorized ability to cause a hang or frequently repeatable crash of MySQL Server, leading to a denial of service. The issue is related to errors in resource release in the InnoDB component.
Recommendations
For MySQL Server versions 5.7.28 and prior, update to a version later than 5.7.28 to resolve the issue.
For MySQL Server versions 8.0.18 and prior, update to a version later than 8.0.18 to resolve the issue.
As a temporary workaround, consider restricting network access to the MySQL Server to minimize the risk of exploitation.
Fix
