The H-Online: As expected, Apple has released an updated version of the Java implementation for its Mac OS X operating system that includes a removal tool for the Flashback trojan. According to the company, the update, labelled “Java for OS X 2012-003“, finds and removes the “most common variants” of the malware which had infected approximately 600,000 systems using flaws in the previous version of Java. Additionally, the new Java update for Mac OS X 10.7 Lion prevents Java applets from being automatically executed by disabling the Java web plugin by default. Users can re-enable the automatic execution of Java applets via the Java Preferences application (Applications ➀ Utilities ➀ Java Preferences). However, if the plugin detects that Java applets have not been run for “an extended period of time”, it will automatically disable applet support again. ...

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”. ...
