CVE-2016-9857: An issue was discovered in phpMyAdmin.

Security readout for executives and security teams

CVE-2016-9857 is a cross-site scripting issue in phpMyAdmin caused by weak JavaScript processing. Affected versions are old 4.6.x, 4.4.x, and 4.0.x releases before the listed security updates. It matters most where phpMyAdmin is reachable by administrators or database users. Exposure is likely limited to environments still running old phpMyAdmin branches, especially web-accessible database administration portals. Systems not using phpMyAdmin, or already updated beyond the fixed versions, are not indicated as affected by the bundle. Treat this as a routine but necessary cleanup item unless phpMyAdmin is internet-facing or shared across many administrators. Prioritize exposed admin portals because XSS in database administration tooling can increase account and data-management risk. Mitigation focus: Upgrade phpMyAdmin to 4.6.5, 4.4.15.9, 4.0.10.18, or later as applicable.; Apply distribution security updates, including Gentoo guidance where relevant.; Restrict phpMyAdmin access to trusted administrative networks or VPN paths..
