Within hours (minutes ??) Google also released a bug fix update Chrome 25. 25.0.1364.160 for Windows, Mac, and Linux and fixes a Type confusion in WebKit.
As per MWR labs blog, they demonstrated a full sandbox bypass exploit against the latest stable version of the Google Chrome 25.0.1364.152 browser on a Windows 7 laptop.
MWR demonstrated that by visiting a malicious webpage, it was possible to exploit a vulnerability, gain code execution in the sandboxed renderer process and bypass the sandbox with system privileges.
Again, this is a history of sorts. Google Chrome fixing a browser within 24 hours of a security exploit disclosure. So update to Google Chrome 25.0.1364.160, to close the breach.
Way to go Google and Mozilla. Quick work. Impressive!
