Version 5.0.375.127, available for Windows, Mac, and Linux PCs, comes roughly three weeks after a security patch that fixed five Chrome flaws. Google usually updates Chrome every 2 to 4 weeks.
Software vulnerability tracker Secunia rates the latest Chrome update as "highly critical," its second-highest ranking after "extremely critical."
One Chrome flaw has an "unknown impact," while others "can be exploited by malicious people to conduct spoofing attacks and compromise a user's system," according to post on Secunia's site.
In addition to the two critical flaws, Chrome 5.0.375.127 patches seven less-serious threats, including one medium and six high-level vulnerabilities. The two most-serious, critical issues include a crash on system shutdown due to a notifications bug, and memory corruption with the file dialog, according to Google.
Chrome, known for its speed and security, has gained market share over the past year, much at the expense of Mozilla Firefox. Microsoft Internet Explorer has recently reversed its declining position and is also gaining share globally, according to Net Applications statistics.
