The security upgrade is now available in the Windows version of Chrome; a Mac OS X version is forthcoming
Google today announced it had wrapped up work on a stronger Flash sandbox in the Windows version of Chrome, and would soon ship the same for its OS X browser.
Chrome 21, which launched July 31, completed efforts to ditch the aged NPAPI (Netscape Plugin Application Programming Interface) Flash plug-in for one built to Google's own PPAPI (Pepper Plugin Application Programming Interface) standard.
By porting Flash Player to PPAPI, Google's engineers were able to stuff the Adobe plug-in into a "sandbox" as robust as the one that protects Chrome itself.
"Windows Flash is now inside a sandbox that's as strong as Chrome's native sandbox, and dramatically more robust than anything else available," Justin Schuh, a Chrome engineer, in a post to the
Chromium blog Wednesday.
