CVE-2017-3599: Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: Server: Pluggable Auth).

Security readout for executives and security teams

This MySQL Server flaw can let an unauthenticated network attacker crash or hang affected database servers. The business impact is service outage, not data theft. Systems running MySQL 5.6.35 or earlier, or 5.7.17 or earlier, should be treated as high-priority if reachable over a network. Exposure is likely where affected MySQL Server versions are still deployed and reachable from untrusted or broad internal networks. Internet-facing database listeners or shared hosting environments raise urgency because no authentication is required. Prioritize remediation for exposed or business-critical MySQL systems because the flaw is unauthenticated, network reachable, and can fully disrupt database availability. Mitigation focus: Apply Oracle April 2017 CPU guidance or later vendor-supported MySQL updates.; For Red Hat builds, apply the relevant RHSA fixed packages.; Restrict MySQL network access to trusted hosts and administrative networks..
