Security readout for executives and security teams

CVE-2018-2762 can let a highly privileged local attacker crash or hang MySQL Server. The business impact is service outage, not data theft or data modification based on the supplied sources. Systems running MySQL Server 5.7.21 or earlier need vendor-guided review and patching. Exposure is limited to supported MySQL Server deployments at version 5.7.21 or prior. Risk is highest where administrators, automation accounts, shared hosting users, or compromised privileged local accounts can log on to infrastructure running MySQL Server. Treat this as a targeted availability risk. It is not described as remotely exploitable and needs high privileges, but database outages can disrupt operations. Patch during the next appropriate maintenance window, sooner for critical MySQL services. Mitigation focus: Apply Oracle CPU April 2018 or downstream vendor updates where applicable.; Review Red Hat, Ubuntu, and NetApp advisories for packaged product applicability.; Prioritize internet-facing or business-critical database hosts for version review..
