Question 2

Is Google Chrome 18 still supported?

Accepted Answer

Google Chrome 18 is no longer supported — it has passed its end of life date (April 24, 2012). No further security patches will be issued. Upgrade to a supported version or obtain extended lifecycle support.

Question 3

When does Google Chrome 18 reach end of life?

Accepted Answer

Google Chrome 18 reached (or will reach) end of life on April 24, 2012. After this date, no security patches or bug fixes are issued by the vendor.

Question 4

What are the security risks of running Google Chrome 18 after end of life?

Accepted Answer

After end of life, the vendor's standard support for Google Chrome 18 ends, so newly discovered vulnerabilities may never be fixed unless a paid extended support option covers that version. Auditors ask about it too: PCI DSS requirement 12.3.4, for example, calls for a yearly review of vendor end-of-life announcements with a remediation plan approved by senior management.
