In addition, our ongoing internal security work was as usual responsible for a wide range of fixes: [241595] High CVE-2013-2836: Various fixes from internal audits, fuzzing and other initiatives. Many of the above bugs were detected using AddressSanitizer. This build also contains a new Adobe Flash build. You can find more information here. Full details about what changes are in this build are available in the SVN revision log. Interested in switching release channels? Find out how.

Last month’s Chrome Beta release contained optimizations so that web pages load 5% faster on average. We’ve included those optimizations in today’s Chrome Stable release so all users will enjoy a faster browsing experience. A 5% improvement may not seem like much by itself, but our estimates show that when you add up those saved seconds across all Chrome users, it totals to more than 510 years of people’s time saved every week. Want to make that number even bigger? Download Chrome today. Posted by James Simonsen, Software Engineer and Saver of Split Seconds

AddressSanitizer (ASAN) is a tool for finding memory problems and has been used to find thousands of memory errors in Chromium over the last two years. These kinds of errors will typically lead to heap or data corruption and subsequent crashes in random, unrelated code, which make them quite challenging to find and fix without tools like ASAN. However, ASAN is built using LLVM/Clang and is limited to Mac and Linux builds of Chromium. To address the lack of coverage for Windows-only code, we built SyzyASAN. SyzyASAN is built on top of the Syzygy toolchain and is an instrumentation-based clone of ASAN for detecting heap errors. It consists of three parts: An instrumenter that injects instrumentation into binaries produced by the Microsoft Visual Studio toolchain.A run-time library that replaces malloc, free, et al.An RPC-based logging server that receives information about detected errors. This lets us get information safely out of sandboxed processes, like Chromium’s renderer.SyzyASAN operates nearly identically to ASAN, finding errors in the same manner and producing similar reports. SyzyASAN finds some of the hardest-to-locate memory bugs like use-after-free, buffer overruns, and underruns. Focusing on very common memory errors allows SyzyASAN to be relatively efficient. Although Chrome with SyzyASAN is very usable, the penalties in speed - 4.7x on CPU intensive operations - and memory - a 25% increase plus a fixed 256MB increase in each process - are noticeable so we’ll confine these releases to our Canary channel for now. We’ve been releasing SyzyASAN-instrumented builds to the Windows Canary channel one day each week recently. One day with a little slowdown on the Canary channel gives us plenty of great data. In the last three weeks, we’ve found 150 new bugs in Chromium, several of which could lead to security vulnerabilities. We’ve put together some instructions for instrumenting your local build and debugging issues. Try it out and help us squash more memory bugs. The Syzygy source code and binaries can be downloaded from our code site, and instructions for how to use it are on our wiki. If you have any questions, suggestions or contributions, feel free to contact syzygy-team@chromium.org. If you’re using Syzygy or SyzyASAN with your project we’d love to hear about it!

[Cross-posted from the Official Google Blog] This morning, we kicked off the 6th annual Google I/O developer conference with over 6,000 developers at Moscone Center in San Francisco, 460 I/O Extended sites in 90 countries, and millions of you around the world who tuned in via our livestream. Over the next three days, we’ll be hosting technical sessions, hands-on code labs, and demonstrations of Google's products and partners' technology. We believe computing is going through one of the most exciting moments in its history: people are increasingly adopting phones, tablets and newer type of devices. And this spread of technology has the potential to make a positive impact in the lives of people around the world—whether it's simply helping you in your daily commute, or connecting you to information that was previously inaccessible. This is why we focus so much on our two open platforms: Android and Chrome. They enable developers to innovate and reach as many people as possible with their apps and servic

We are currently updating Flash Player to 11.7.700.202 for Windows and Mac to all Stable channel (Chrome 26) users. If you find a new issue, please let us know by filing a bug. Anthony LaforgeGoogle Chrome
