CVE-2018-3070: Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: Client mysqldump).

Security readout for executives and security teams

This is a denial-of-service issue in Oracle MySQL Server involving the mysqldump client subcomponent. A low-privileged network user could make affected MySQL versions hang or repeatedly crash, disrupting database-backed applications without evidence of data theft or modification from the supplied sources. Exposure is most likely where older Oracle MySQL Server 5.5, 5.6, or 5.7 instances remain reachable by low-privileged users over the network. Downstream packaged deployments should be checked against Oracle, Ubuntu, Red Hat, Debian, and NetApp advisories. Treat this as a service availability risk. It is not described as data compromise, but outage potential can be business-impacting for systems still running old MySQL versions or allowing broad database network access. Mitigation focus: Upgrade MySQL beyond the affected versions identified by Oracle.; Apply relevant vendor security updates from Oracle or the operating-system distributor.; Restrict MySQL network access to trusted hosts and required users..
