CVE-2017-10155: Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: Server: Pluggable Auth).

Security readout for executives and security teams

CVE-2017-10155 can let an unauthenticated network attacker crash or hang affected Oracle MySQL Server instances. The business impact is service outage rather than data theft, but internet-exposed or widely reachable databases could suffer repeatable downtime until updated or isolated. Exposure is most likely where MySQL Server is running affected 5.6 or 5.7 versions and accepts network connections from untrusted users, application tiers, partner networks, or the internet. Treat as high priority for exposed or critical MySQL services because a remote unauthenticated outage is plausible. It is less urgent than data compromise, but downtime can directly affect revenue, operations, and dependent applications. Mitigation focus: Inventory MySQL Server versions and flag 5.6.37 or earlier and 5.7.19 or earlier.; Apply vendor updates from Oracle, Red Hat, NetApp, or your distribution guidance.; Restrict MySQL network access to trusted application hosts and administration networks..
