After many years of dealing with site compatibility issues, Opera found the solution: it will switch from its proprietary rendering engine (Presto) to WebKit and will be powered by Chrome’s open source version, Chromium. “Presto is a great little engine. It’s small, fast, flexible and standards compliant while at the same time handling real-world web sites. It has allowed us to port Opera to just about any platform you can imagine. (…) It was always a goal to be compatible with the real web while also supporting and promoting open standards. That turns out to be a bit of a challenge when you are faced with a web that is not as open as one might have wanted. Add to that the fact that it is constantly changing and that you don’t get site compatibility for free (which some browsers are fortunate enough to do), and it ends up taking up a lot of resources – resources that could have been spent on innovation and polish instead,” explains an Opera employee. ...

h-online: Google has updated the Stable, Beta and Developer Channels of the desktop version of its Chrome browser with a number of bug fixes and improvements. The Stable Channel update closes seven security vulnerabilities, three of them rated High, and includes bug fixes. New stable Chrome versions for iOS and Android have also been released and include minor improvements. The iOS version of the browser now supports Apple’s Passbook application. ...

h-online: With the release of Chrome 21, web applications can now directly access the local system’s built-in camera and microphone. Instead of requiring a special plugin, the major stable update to the WebKit-based web browser includes a new HTML5 [getUserMedia](http://www.html5rocks.com/en/tutorials/getusermedia/intro/) API – currently a W3C Editor’s Draft – to provide web apps with access to the camera and microphone. For security purposes, users will be prompted to grant apps permission to access the hardware. ...

Google has published a new update to the stable 20.x branch of Chrome to close a number of security holes in the WebKit-based web browser. Version 20.0.1132.57 of Chrome addresses a total of three vulnerabilities, all of which are rated as “high severity” by the company. These include two use-after-free errors in counter handling and in layout height tracking that were discovered by a security researcher by the name of “miaubiz”. As part of its Chromium Security Vulnerability Rewards program, Google paid the researcher, who is number three in the company’s Security Hall of Fame, $1,000 for discovering and reporting each of the holes. A third high-risk problem related to object access with JavaScript in PDFs has also been corrected. As usual, further details about the vulnerabilities are being withheld until “a majority of users are up-to-date with the fix”. Other changes include stability improvements, and updates to the V8 JavaScript engine and the built-in Flash player plug-in. ...

Google has closed a total of 23 vulnerabilities with the release of Chrome 20. Of those vulnerabilities, 14 are rated critical, enabling attackers to execute code in the browser’s sandbox, among other things. Integer overflow vulnerabilities in the code for processing PDF files and Matroska containers (.mkv) have also been fixed. Chrome 20 also includes the latest version of Adobe’s Flash Player on Linux, using the new cross-platform Pepper API. In testing at The H, it was confirmed that the Flash Player support also works on 64-bit Linux systems. ...

H-Online: Google has announced an update to the stable version of Chrome, which brings the browser version to 19.0.1084.52 on Windows, Mac OS X and Linux. The update is a pure security update that does not include any new features – it closes nine vulnerabilities with a Common Vulnerability Scoring System (CVSS) rating of “High” and fixes two problems labelled “Critical” as well as two “Medium” level issues. Many of the vulnerabilities are due to bugs in Chrome’s memory handling, such as out-of-bounds reads and use-after-free conditions, and Google points out that several of them were detected with their AddressSanitizer tool. Other bugs were fixed in Chrome’s PDF handling code and its V8 JavaScript rendering engine. ...

The H-Online: Google has announced that Chrome 19 is the new stable version of its open source based web browser. As usual, the browser sees a number of security fixes: this time there are seven high-severity fixes specifically for Chrome including various use-after-free and out-of-bounds errors. Two fixes with a wider impact than Chrome are also mentioned – a workaround for a Linux NVIDIA driver bug and an “off-by-one out-of-bounds” write in libxml. In all, $7500 was paid out in rewards to security researchers, and Google notes it has also paid out $9000 to researchers to stamp out bugs before they reached its stable channel. ...

The H-Online: Google has released a new update to the stable 18.x branch of its Chrome web browser to close a number of security holes found in the application. The update, labelled 18.0.1025.168, addresses a total of five vulnerabilities, three of which are rated as “high severity” by the company. These include use-after-free problems in floating point handling and the XML parser; all of these bugs were detected using the AddressSanitizer. As part of its Chromium Security Vulnerability Rewards program, Google paid a security researcher by the name of “miaubiz”, who is number three in the company’s Security Hall of Fame, $1,000 for discovering and reporting one of the float handling problems. Two medium risk problems related to IPC validation and a race condition in sandbox IPC have also been corrected. ...

The H-Online: Google has announced updates to the Stable and Beta channels of their Chrome browser, fixing several bugs and twelve security vulnerabilities. Seven of the twelve security fixes were classed as high-risk problems and Google paid a total of $6000 to the researchers who discovered the bugs. The update also includes a new version of the bundled Flash Player. Adobe have revised the Flash Player advisory from the end of March to include fixes for a Chrome/Flash only pair of memory corruption issues listed as CVE-2012-0724 and CVE-2012-0725. Given that these issues only affect Chrome and Chrome manages its own update, it is unlikely that Adobe will be reissuing or updating the advisory or patches for other browsers and platforms. ...

Google has released version 18 of Chrome, the company’s own extended version of the open source Chromium web browser. The new Stable channel release, labeled 18.0.1025.142, fixes several security vulnerabilities, and improves graphics and drawing performance on systems with capable hardware. This is done by adding support for GPU-accelerated rendering of 2D Canvas content on Windows and Mac OS X systems. According to the developers, the GPU acceleration should improve the overall performance of graphics-intensive web applications, making canvas-based animations and games “run faster and feel smoother”. For older systems that can’t make use of of the GPU, Chrome can now display 3D content using the SwiftShader software rasterizer, which Google licensed from TransGaming, Inc. However, the developers note that “a software-backed WebGL implementation is never going to perform as well as one running on a real GPU, but now more users will have access to basic 3D content on the web”. ...

The H-Security: Google has released version 17.0.963.83 of its Chrome web browser, a maintenance update that fixes issues with Flash games and closes several security holes. The Stable channel update addresses a total of nine vulnerabilities, six of which are rated as “high severity“. These include an integer issue in libpng (the official PNG reference library), a memory corruption problem in WebGL canvas handling and a cross-origin violation related to “magic iframe”, as well as use-after-free errors in first-letter handling, CSS cross-fade handling and block splitting. One medium-risk invalid read in the V8 JavaScript engine and two low-risk problems related to WebUI privileges and unpacked extension installation have also been fixed. ...

The H-Security: Google has released a new stable version of its Chrome browser. The update fixes seventeen high severity vulnerabilities and updates the bundled Flash player. Google referred users to Adobe for details of the Flash Player update, and as usual, revealed few details about the seventeen holes that it closed in the release. It did, though, say that the researchers earned between $500 and $3000 for their vulnerability disclosures. ...

Google is to offer up to a million dollars in rewards for Chrome exploits at the CanSecWest conference. Previously, Google has sponsored the Pwn2Own competition which is held at CanSecWest, but has decided that this year it will directly reward exploits. “We discovered that contestants are permitted to enter Pwn2Own without having to reveal full exploits (or even all of the bugs used!) to vendors” says Google in a blog post. In previous years, full details have been handed over, but the revised rules make it “an explicit non-requirement in this year’s contest” – a change that Google calls “worrisome”. The organizers revised the rules to make the contest “more fair” and “more of a competition”. ...

The H-Online: Google’s solution for the problem of getting better passwords on the net – a combination of browser sign-in andOpenID – will take some time to implement as it involves persuading sites to switch to using OpenID. The developers on the Chrome project think that they can at least improve the security of passwords on sites, by generating passwords for the user. A new Password Generation proposal for the Chromium and Chrome browsers attempts to address that by assuming that once the user is signed into the browser, it can take over the handling of password creation. ...
