Google has updated its Chrome web browser for three high-risk vulnerabilities, bringing the program to version number 16.0.912.77. Google’s release notes point out that one of the bugs, regarding Safe Browsing navigation, “was fixed in 16.0.912.75 but accidentally excluded from the release notes,” so this release actually mentions four vulnerabilities, but only actually fixes three of them.
The Chrome browser auto-updates on Mac OS X, so you don’t have to worry about downloading a new version.
