Description

A flaw was found in the Security: Encryption component of MySQL. This issue may allow an attacker to impact the confidentiality, integrity, and/or availability of MySQL Server depending on the vulnerability details. Refer to the Oracle CPU advisory for component-specific impact.

Statement

This vulnerability is rated as having Moderate impact because, while a successful exploit can cause a complete denial of service by terminating or hanging the database daemon, exploitation requires high attack complexity and existing low-privileged authentication credentials. The security flaw is confined to availability without compromising data confidentiality or integrity. Typical Red Hat Enterprise Linux deployments isolate database services within private networks or restrict direct access to authorized application tiers, substantially limiting exposure to untrusted parties.
