CVE-2019-2455: Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: Server: Parser).

Security readout for executives and security teams

CVE-2019-2455 is a denial-of-service flaw in Oracle MySQL Server's parser. A low-privileged user who can reach MySQL over the network could make the database hang or repeatedly crash. The main business risk is application downtime, not data theft or data modification. Exposure is most likely where affected MySQL servers accept network connections from low-privileged users, shared application accounts, partner networks, or less-trusted internal systems. Internet-exposed MySQL would materially increase urgency. Prioritize remediation for business-critical or externally reachable MySQL servers. This is not presented as a data compromise issue, but database denial of service can still cause material application outages. Mitigation focus: Apply Oracle MySQL security updates per the January 2019 CPU or your OS vendor advisory.; For Ubuntu, Red Hat, and NetApp deployments, follow the listed vendor advisories.; Restrict MySQL network access to trusted application hosts and administration networks..
