**Name of the Vulnerable Software and Affected Versions** MySQL Client versions 5.6.47 and prior MySQL Client versions 5.7.27 and prior MySQL Client versions 8.0.17 and prior **Description** The issue is related to the C API component of the MySQL Client product, which has inadequate access control. This allows a low-privileged attacker with network access via multiple protocols to compromise the MySQL Client. Successful attacks can result in the unauthorized ability to cause a hang or frequently repeatable crash of the MySQL Client, leading to a denial of service. The vulnerability can be exploited remotely through the MySQL Protocol. **Recommendations** For versions 5.6.47 and prior, update to a version later than 5.6.47 to resolve the issue. For versions 5.7.27 and prior, update to a version later than 5.7.27 to resolve the issue. For versions 8.0.17 and prior, update to a version later than 8.0.17 to resolve the issue. As a temporary workaround, consider restricting network access to the MySQL Client to minimize the risk of exploitation.
