Mozilla offers temporary fix for Firefox flaw

Filed under
Moz/FF

Responding to the disclosure of a serious Web browser flaw, the Mozilla Foundation offered on Friday a temporary fix to protect Firefox and Mozilla users.

The downloadable fix protects against attacks that take advantage of a new, unpatched flaw that could let attackers secretly run malicious software on users' PCs. The flaw was disclosed late Thursday by security researcher Tom Ferris, sending Mozilla staff into damage-control mode.

"This is a temporary work-around just to deal with the immediate issue," Schroepfer said. "We're working on a future release in which we will actually fix the problem and re-enable the IDN feature." Switching off IDN support impacts a subset of Firefox and Mozilla users who actually use such special domain names, he said.
Though there is no known attack that takes advantage of the flaw, Mozilla advises Firefox and Mozilla users to disable IDN. "Luckily we do not have any known use of this exploit, but it is fairly critical if there were to be (an attack), so this is a recommended download," Schroepfer said.

In addition to the downloadable fix, Mozilla on its Web site also offers instructions to manually disable IDN: Type "about:config" in the address bar, hit Enter; type "network.enableIDN" in the filter toolbar, hit Enter; right-click the "network.enableIDN" item and select Toggle to change value to false.

  • The End of Gmane?
    In 2002, I grew annoyed with not finding the obscure technical information I was looking for, so I started Gmane, the mailing list archive. All technical discussion took place on mailing lists those days, and archiving those were, at best, spotty and with horrible web interfaces. The past few weeks, the Gmane machines (and more importantly, the company I work for, who are graciously hosting the servers) have been the target of a number of distributed denial of service attacks. Our upstream have been good about helping us filter out the DDoS traffic, but it’s meant serious downtime where we’ve been completely off the Internet.

    Pwnie Express has given the keys to software used to secure the Internet of Things (IoT) and Android software to the open-source community. The Internet of Things (IoT), the emergence of devices ranging from lighting to fridges and embedded systems which are connected to the web, has paved an avenue for cyberattackers to exploit.

    Open-source components play a key role in the software supply chain. By reducing the amount of code that development organizations need to write, open source enables companies to deliver software more efficiently — but not without significant risks, including defective and outdated components and security vulnerabilities.

Chew on this: Ubuntu Core Linux comes to the uCRobotics Bubblegum-96 board

Linux and other open source software have been in the news quite a bit lately. As more and more people are seeing, closed source is not the only way to make money. A company like Red Hat, for instance, is able to be profitable while focusing its business on open source. Ubuntu is one of the most popular Linux-based operating systems, and it is not hard to see why. Not only is it easy to use and adaptable to much hardware (such as SoC boards), but there is a ton of free support online from the Ubuntu user community too. Today, Canonical announces a special Ubuntu Core image for the uCRobotics Bubblegum-96 board. Read more
