So far this year, Google has paid more than $230,000 to outside researchers for submitting Chrome vulnerabilities. More than half of that -- $120,000 -- was laid out in March at "Pwnium," a Google-sponsored hacking challenge.
Tuesday's update was the 13th this year that patched one or more vulnerabilities.
According to the latest figures from metric company Net Applications, Chrome has a usage share of about 19%. Irish measurement firm StatCounter, on the other hand, pegged Chrome's share for April at 31%.
Chrome 19 can be downloaded for Windows, Mac OS X and Linux from Google's website. The browser is updated automatically through its silent service.
