REDHAT-BUG-2504925: Medium severity Oracle MySQL Server vulnerability

Q: What level of access does an attacker need to exploit this issue?

An attacker needs high privileges and network access to the affected MySQL Server or MySQL Cluster instance. The CVSS vector indicates no user interaction is required, but exploitation has high attack complexity.

Q: What is the expected impact if exploitation succeeds?

Successful exploitation can cause the affected MySQL Server or MySQL Cluster service to hang or crash repeatedly, resulting in a complete denial of service. The provided assessment lists no confidentiality or integrity impact.

Q: Which releases are identified as affected?

Affected MySQL Server releases are 8.4.0 through 8.4.10 and 9.7.0 through 9.7.1. Affected MySQL Cluster releases are 8.0.0 through 8.0.47, 8.4.0 through 8.4.10, and 9.7.0 through 9.7.1.

Remediation

Recommended actions to resolve this vulnerability, in priority order.

Compensating control
Mitigate the availability impact by restricting network access to the MySQL Server/MySQL Cluster services (e.g., firewall/ACL allow only required client networks and deny all other inbound traffic) to reduce exposure to network-reachable exploitation via multiple protocols.
