In the early days of the Web this provided a tremendous advantage, because it allowed third-party plug-ins to evolve rapidly and implement new capabilities, moving the whole web forward. <br /> <br /> Unfortunately, as the web evolved, the past benefits of NPAPI became liabilities. The thinness allowed legacy browser and OS behavior to bleed through and crystallize to the point that it hamstrung future improvements. As browsers add compelling features like sandboxing, GPU acceleration, and a multi-process architecture, the legacy of NPAPI severely impedes or outright prevents us from extending those improvements to any pages with plug-in content. <br /> <br /> By porting Flash to PPAPI we’ve been able to achieve what was previously impossible with NPAPI for the <a href="http://blog.chromium.org/2012/07/npapi-plug-ins-in-windows-8-metro-mode.html">99.9% of Chrome users that rely on Flash</a>. Windows Flash is now inside a sandbox that’s as strong as Chrome’s native sandbox, and dramatically more robust than anything else available. And for the first time ever, Windows XP users (specifically, over 100 million Chrome users) have a sandboxed Flash—which is critical given the absence of OS support for security features like <a href="http://en.wikipedia.org/wiki/Address_space_layout_randomization">ASLR</a> and <a href="http://en.wikipedia.org/wiki/Mandatory_Integrity_Control">integrity levels</a>. <br /> <br /> Beyond the security benefits, PPAPI has allowed us to move plug-ins forward in numerous other ways. By eliminating the complexity and legacy code associated with NPAPI, we’ve reduced Flash crashes by about 20%. We can also composite Flash content on the GPU, allowing faster rendering and smooth scrolling (with more improvements to come). And because PPAPI doesn’t let the OS bleed through, it’s the only way to use all Flash features on any site in Windows 8 Metro mode. <br /> <br /> Moving forward, we’re finishing off the PPAPI Flash port for Mac OS X and hope to ship it soon.

And because PPAPI doesn’t let the OS bleed through, it’s the only way to use all Flash features on any site in Windows 8 Metro mode. <br /> <br /> Moving forward, we’re finishing off the PPAPI Flash port for Mac OS X and hope to ship it soon. And Linux users have already been benefiting from PPAPI Flash since Chrome 20, along with Chrome OS users who have been running it for almost a year. Soon all Chrome users will have access to the improved security, stability, and performance of PPAPI Flash. <br /> <br /> <span class="post-author">Posted by Justin Schuh, Software Engineer and Boring Security Guy</span> <span itemprop='author' itemscope='itemscope' itemtype='http://schema.org/Person'> <meta content='https://plus.google.com/116899029375914044550' itemprop='url'/> </span> </noscript> </div> </div> <div class='share'> <span class='twitter-custom social-wrapper' data-href='http://twitter.com/share?text=Chromium Blog:The road to safer, more stable, and flashier Flash&url=https://blog.chromium.org/2012/08/the-road-to-safer-more-stable-and.html&via=ChromiumDev'> <img alt='Share on Twitter' height='24' src='https://www.gstatic.com/images/icons/material/system/2x/post_twitter_black_24dp.png' width='24'/> </span> <span class='fb-custom social-wrapper' data-href='https://www.facebook.com/sharer.php?u=https://blog.chromium.org/2012/08/the-road-to-safer-more-stable-and.html'> <img alt='Share on Facebook' height='24' src='https://www.gstatic.com/images/icons/material/system/2x/post_facebook_black_24dp.png' width='24'/> </span> </div> <div class='post-footer'> <div class='cmt_iframe_holder' data-href='https://blog.chromium.org/2012/08/the-road-to-safer-more-stable-and.html' data-viewtype='FILTERED_POSTMOD'></div> <a href='https://plus.google.com/112374322230920073195' rel='author' style='display:none;'> Google </a> <div class='label-footer'> </div> </div> </div> <div class='post' data-id='1301743313806415297' itemscope='' itemtype='http://schema.org/BlogPosting'> <h2 class='title' itemprop='name'> <a href='https://blog.chromium.org/2012/08/ending-mixed-scripting-vulnerabilities.html' itemprop='url' title='Ending mixed scripting vulnerabilities'> Ending mixed scripting vulnerabilities </a> </h2> <div class='post-header'> <div class='published'> <span class='publishdate' itemprop='datePublished'> Friday, August 3, 2012 </span> </div> </div> <div class='post-body'> <div class='post-content' itemprop='articleBody'> <script type='text/template'> Last year, we posted on the Google Online Security Blog about our desire to <a href="http://googleonlinesecurity.blogspot.com/2011/06/trying-to-end-mixed-scripting.html">end mixed scripting vulnerabilities</a>.

Instead, if you see the shield icon, we recommend contacting the website owners to make sure they know they may have a security vulnerability.<br /> <br /> It has been an interesting journey to get to this point. For about a year, we blocked mixed scripting by default on Chrome’s Dev and Beta channel releases. Rolling out the block to Stable was more challenging because of widespread mixed scripting across the web. To move forward, we turned blocking on for certain web sites, starting with <span class="Apple-style-span" style="font-family: 'Courier New', Courier, monospace;">google.com</span>. Later, we reached out to and then collaborated with <span class="Apple-style-span" style="font-family: 'Courier New', Courier, monospace;">twitter.com</span> and <span class="Apple-style-span" style="font-family: 'Courier New', Courier, monospace;">facebook.com</span> to opt them into blocking, too. All these websites hold themselves to a high standard of security, so this approach worked well. We later took the additional step of <a href="https://code.google.com/p/chromium/issues/detail?id=100136">opting in sites to mixed script blocking</a> for any site using the HSTS standard.<br /> <br /> We bit the bullet and let full mixed script blocking for all sites hit Stable back in Chrome 19. Predictably, we uncovered a range of buggy web sites, and some users were confused about the “infobar” warning displayed by the older versions of Chrome:<br /> <br /> <a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhnzQtSYfkPjgNRTR3ij9-etb-jHyws1s4yOsdzyEgddxvfm2f9szd8w164S6gNh-pxJNCDDVdGE0l75OWAhKcCJQiGHYsHcQEJvhmWR1szOJ4-BusizwQtfpy-L6IEM_OcW7tyOWAvF6o/s1600/Screen+shot+2012-08-03+at+10.52.45+AM.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="58" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhnzQtSYfkPjgNRTR3ij9-etb-jHyws1s4yOsdzyEgddxvfm2f9szd8w164S6gNh-pxJNCDDVdGE0l75OWAhKcCJQiGHYsHcQEJvhmWR1szOJ4-BusizwQtfpy-L6IEM_OcW7tyOWAvF6o/s400/Screen+shot+2012-08-03+at+10.52.45+AM.png" width="400" /></a> <br /> <br /> Fortunately—and no doubt driven by the high visibility of this warning—some prominently affected websites were able to deploy quick fixes to resolve their mixed scripting vulnerabilities.
