Name of the Vulnerable Software and Affected Versions
MySQL Cluster versions 7.4.34 and prior
MySQL Cluster versions 7.5.24 and prior
MySQL Cluster versions 7.6.20 and prior
MySQL Cluster versions 8.0.27 and prior
Description
The issue is related to a buffer read overflow in the memory of the MySQL Cluster system, which can be exploited by a remote attacker to disclose protected information or cause a partial denial of service. The vulnerability is difficult to exploit and requires a high-privileged attacker with access to the physical communication segment attached to the hardware where the MySQL Cluster executes. Successful attacks also require human interaction from a person other than the attacker, and can result in unauthorized read access to a subset of MySQL Cluster accessible data and unauthorized ability to cause a partial denial of service of MySQL Cluster.
Recommendations
For MySQL Cluster versions 7.4.34 and prior, update to a version later than 7.4.34.
For MySQL Cluster versions 7.5.24 and prior, update to a version later than 7.5.24.
For MySQL Cluster versions 7.6.20 and prior, update to a version later than 7.6.20.
For MySQL Cluster versions 8.0.27 and prior, update to a version later than 8.0.27.
As a temporary workaround, consider restricting access to the physical communication segment attached to the hardware where the MySQL Cluster executes to minimize the risk of exploitation.
