CVE-2024-21135

Name of the Vulnerable Software and Affected Versions: Oracle MySQL Server versions 8.0.36 and prior Oracle MySQL Server versions 8.3.0 and prior

Description: The issue is related to the Server: Optimizer component of Oracle MySQL Server and is caused by incorrect resource cleanup or deallocation. 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 Oracle MySQL Server versions 8.0.36 and prior, update to a version later than 8.0.36 to resolve the issue. For Oracle MySQL Server versions 8.3.0 and prior, update to a version later than 8.3.0 to resolve the issue. As a temporary workaround, consider restricting network access to the MySQL Server to minimize the risk of exploitation.
