Google has fixed seven security flaws in Chrome, just a day before the annual, real-time hacking competitions Pwnium and Pwn2Own.
The new security update for Chrome on Windows, Mac, and Linux patched four flaws labeled as High, below the more important level of Critical; three flaws in its rendering engine V8; and updated its internal version of Flash Player.
Three High-level vulnerabilities were found by three independent researchers, who earned a total of $8,000 for their work. The last High-level vulnerability was discovered by Google employees, as were the V8 vulnerabilities.
