Mozilla releases Firefox 16.0.1 to address four vulnerabilities

Mozilla releases Firefox 16.0.1 one day after pulling Firefox 16 from download because of a security issue

Mozilla released Firefox 16.0.1 on Thursday in order to fix a publicly disclosed vulnerability and three other security flaws identified after the release of Firefox 16.

Mozilla pulled down Firefox 16 from its website on Wednesday, one day after its release, because of a vulnerability that potentially allowed malicious Web pages to read the URLs of other websites accessed by visiting users. Such behavior should normally be prohibited by the browser's security mechanisms.

The issue was publicly disclosed by security researcher Gareth Heyes on Wednesday. Heyes published proof-of-concept code that, when loaded from an arbitrary Web page, could determine the user name of a user logged into Twitter.

Mozilla determined that the issue found by Heyes only affects Firefox 16.0 and addressed it in Firefox 16.0.1.

However, the new version of Firefox also fixes a separate vulnerability discovered by a Mozilla security researcher that can result in a similar behavior. In Firefox 15 and earlier versions this second security issue can also potentially lead to arbitrary code execution.

In addition, Firefox 16.0.1 fixes two memory corruption bugs in the browser engine that can result in crashes and can potentially be exploited to execute arbitrary code. One of these bugs only affects the Android version of Firefox when running inside custom Android firmware like CyanogenMod.

Thunderbird 16.0.1 and SeaMonkey 2.13.1 were also released on Thursday in order to address the same vulnerabilities that were patched in the desktop version of Firefox.

The HP OfficeJet 250 Mobile Printer is a great device that fits perfectly into my fast paced and mobile lifestyle. My first impression of the printer itself was how incredibly compact and sleek the device was.

Wireless printing from my iPhone was also a handy feature, the whole experience was quick and seamless with no setup requirements - accessed through the default iOS printing menu options.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.
