Updates

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. ...

H-Online: Soon, users running Firefox 3.6.x will start being automatically upgraded to the current version 12.0 release of the open source web browser. The plan to auto-update these users has been being discussed since the end of March, when Mozilla Release Manager Alex Keybl proposed the move on a Mozilla planning discussion thread. According to Keybl, Firefox 3.6.x users with updates enabled should start being upgraded in early May – the specific date has yet to be confirmed. The 3.6.x branch of Firefox, the first release of which arrived in January 2010, reached its end of life last week on 24 April; the last update to the 3.6 series was version 3.6.28 from early March. ...

gHacks: Dropbox has just released a stable update that brings all desktop clients of the file synchronization and hosting service to 1.4. Feature-wise, it is not really a big change to previous versions, especially not so if you have been running experimental versions of the client before. When you look at the new feature set, you will notice that photo import from cameras, phones and SD cards is on top of that list. This is followed by a new batch upload and download option for files, and smaller cosmetic changes, like a fix for the missing camera upload icon on Mac OS X, or new tour screens for first time users. ...

The H-Online: The PHP developers have released the first update for PHP 5.4, the latest version of their popular scripting language, and an update to PHP 5.3, the older stable branch of the language. The developers say “All users of PHP are strongly encouraged to upgrade” to the new releases. PHP 5.4.1 has more than 20 bug fixes, including some related to security. One security bug concerned insufficient validating of the an upload name, which then led to corrupted $_FILES indices. Another notable change was open_basedir checks being added to readline_write_history and readline_read_history. ...

The H-Online: A beta of version 12 of the Opera web browser has been released with privacy and security-focused improvements. Code-named “Wahoo”, the Opera 12.00 beta now runs plugins out-of-process and includes optimizations for better SSL handling. Running plugins in their own process not only improves the smoothness and stability of the browser but can limit the damage some plugin exploits can do. Privacy is enhanced with support for the “Do Not Track” (DNT) header, which is used to tell web sites that the browser user wishes to opt-out of online behavioral tracking. ...

Cnet: Microsoft today made available for download a new release of its free anti-virus/anti-malware program for Windows PCs, Microsoft Security Essentials (MSE). The MSE 4.0 release is available via the Microsoft Download Center and the MSE Web site. (I learned of its availability from a post on Neowin today.) The latest version runs on Windows XP, Windows Vista, and Windows 7. The 4.0 version has been in beta since late 2011. As ZDNet sister site TechRepublic reported back in December 2011, Microsoft officials said the 4.0 release would include a streamlined interface; a renamed version of the SpyNet service (now slated to be known as Microsoft Active Protection Services); new automatic remediation functionality; and overall improved performance and detection capabilities. ...

Mozilla has released new final versions of Firefox 12 and Thunderbird 12, its open source browser and email messaging tools. Neither update, despite the new version number, contains much in the way of exciting new features, but developments on future builds suggest version 13 could be a landmark release for both. Firefox 12 introduces one notable change for Windows users — the advent of silent updates with no User Account Control dialog getting in the way, while Thunderbird 12’s headline new feature is the ability to view message extracts in global search results. ...

The H-Security: The Ruby development team has published an update to the 1.9.3 series of its open source programming language to fix a vulnerability found in the RubyGems package management framework. The maintenance release of the scripting language, labelled 1.9.3-p194, updates RubyGems to close a security hole that caused SSL server verification to fail for remote repositories. This has been addressed by disallowing redirects from https to http connections and by enabling the verification of server SSL certificates in an updated version of RubyGems, 1.8.23; more details on these issues are provided in the latest RubyGems History file. The developers encourage those who use https source in .gemrc or /etc/gemrc to upgrade as soon as possible. ...

The H-Security: The developers of the popular open source blog engine WordPress have released a security update for the software. WordPress 3.3.2 fixes unspecified bugs in three external file upload libraries used in the software and other security problems with the application. The bugs affect both WordPress’s current file uploading library Plupload as well as the SWFUpload and SWFObject libraries; these were bundled with older versions of the application and might still be in use by certain plugins on the current versions of WordPress. The developers did not go into detail about the specifics of the security holes but thanked three people from the WordPress community for responsibly disclosing them. Three more fixes address a privilege escalation in the blog engine’s multi-site system and two cross-site scripting vulnerabilities in the core components of WordPress. More details on all of these patches and also some additional smaller fixes can be found in the change log. ...

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 ➤ Utilities ➤ 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: A new version of NVIDIA’s proprietary UNIX graphics drivers for Linux, Solaris and FreeBSD fixes a security vulnerability (CVE-2012-0946) that allowed attackers to read and write arbitrary system memory in order to, for example, obtain root privileges. To take advantage of the vulnerability, an attacker must have access permission for some device files – which, for systems with these drivers, is typically the case for users who can launch a graphical interface as 3D acceleration and some other features cannot be used otherwise. ...

The H-Online: The Tuesday after the Easter weekend, 10 April, is set to be a busy one for system administrators as Microsoft and Adobe have sent out notifications that they will both be issuing fixes for critical vulnerabilities in their products. Microsoft’s April notification says there will be four critical advisories concerning Microsoft Windows, Internet Explorer, .NET Framework, Office, SQL Server, Microsoft Server and Developer tools, which all lead to remote code execution. A fifth remote code execution vulnerability in Office is marked as important, as is a sixth information disclosure issue in Microsoft’s Forefront United Access Gateway. The critical bulletins will affect all versions of Windows, from Windows XP SP3 to Windows Server 2008R2. One critical bulletin for Internet Explorer covers IE 6, 7, 8 and 9 ...

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. ...

SophosLabs: Adobe released Flash Player version 11.2.202.228 for Windows, OS X and Linux today. In my view this is a milestone release as it finally introduces an automatic, silent updating mechanism to help users stay current with the latest releases from here forward. Google Chrome users may consider themselves spoiled, as they have been enjoying the worry-free joy of automatic updating of both their browser and integrated plugins like Flash Player for quite some time. ...

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”. ...
