CVE-2019-2695: Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: Server: Optimizer).

Security readout for executives and security teams

CVE-2019-2695 is a denial-of-service issue in Oracle MySQL Server's optimizer. A low-privileged network user could make affected MySQL Server versions hang or crash repeatedly, disrupting applications that depend on the database. The bundle does not show data theft or data modification impact. Exposure is most likely where MySQL Server 8.0.15 or earlier accepts network connections from authenticated low-privileged users. Internet exposure is not required, but any reachable database service with broad user access increases operational risk. Treat this as a reliability risk for business systems that depend on MySQL. Prioritize patching exposed or shared database environments first, especially where many low-privileged users or applications can connect. Mitigation focus: Identify all Oracle MySQL Server deployments at version 8.0.15 or earlier.; Apply vendor updates using Oracle CPU Apr 2019 or relevant Red Hat errata guidance.; Restrict MySQL network access to trusted application hosts and administration networks..
