ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

An attacker can affect database-server availability, resulting in partial denial of service. Available assessments identify no confidentiality or integrity impact.

Mitigation

If you can’t patch tonight, do this now.

Restrict local interactive and administrative access to trusted users, apply least privilege to operating-system accounts, and monitor the database service for unexpected availability failures until the update can be installed.

Remediation

Patch, then assume compromise.

Update Oracle MySQL and MariaDB to vendor-fixed releases. For the affected MariaDB branches, update to 10.0.25 or later and 10.1.14 or later, respectively. For Red Hat Software Collections, install the updates supplied by RHSA-2016:0705 for rh-mysql56-mysql and RHSA-2016:1132 for rh-mariadb100-mariadb; the MySQL update upgrades the package to MySQL 5.6.30 and the MariaDB update supplies MariaDB 10.0.25.
