Firefox 3.6 and 3.5 users can obtain their newest versions with the update tool. Users can update to Firefox 4.0.1 by downloading the new edition - which runs on Windows, Mac and Linux - or by selecting "Check for Updates" from the Help menu in the browser. The support expiration for Firefox 3.5 will affect a minority of Mozilla's users: As of the end of March, just 1.7% of all users worldwide were running the browser, according to statistics from Web metrics company Net Application. "All users are encouraged to upgrade to Firefox 4." "This is the last planned security and stability release for Firefox 3.5," said Christian Legnitto, who overseas Firefox releases. Mozilla also upgraded older editions of Firefox to 3.6.17 and 3.5.19, noting that the latter was the last security update for the aged browser.
Nils may be best known for his work at the annual Pwn2Own hacking contest, where in 2009 he exploited Internet Explorer, Firefox and Safari in short order to win $15,000 in cash awards.Īt 2010's Pwn2Own, Nils won $10,000 by sidestepping ASLR and DEP (data execution prevention), another anti-exploit technology found in Windows, to hack Firefox 3.6. Mozilla credited a researcher who goes only by his first name, "Nils," for reporting the ASLR oversight. "WebGL was introduced in Firefox 4 older versions are not affected by these issues." "The WebGLES libraries could potentially be used to bypass a security feature of recent Windows versions," Mozilla acknowledged. It's designed to make it more difficult for attackers to locate addressable memory space that can be used to execute exploits. The Khronos Group, an industry consortium whose members include Mozilla, Google, Opera and Apple, released the final specification of WebGL 1.0 just last month.ĪSLR, or address space layout randomization, is one of the security underpinnings of Windows Vista and Windows 7.
WebGL is supported in shipping versions of Firefox and Google's Chrome, in a preview build of Opera Software's Opera, and will be backed by Safari in its next upgrade.
