Last Thursday Google released an update for Google Chrome bringing it to version 45.0.2454.101. This update addresses 2 high severity CVEs (defined).
Google Chrome updates automatically and will apply the update the next time Chrome is closed and then re-opened. Chrome can also be updated immediately by clicking the Options button (it looks like 3 stacked small horizontal lines) in the upper right corner of the window and choosing “About Google Chrome” from the menu. Follow the prompt to Re-launch Chrome for the update to take effect.
As always full details of the update were made available by Google in a blog post.
