Adobe fixes undisclosed vulnerabilities in Reader

Upgrade to version 8.1.2 available

Adobe has released an update that fixes vulnerabilities in its widely used Reader document viewing program.

Users are urged to upgrade to version 8.1.2, available for download on Adobe's Web site.

Adobe has not given out details of the vulnerabilities, even though the company has a section on its Web site detailing security advisories for Reader.

That could indicate that the vulnerabilities are fairly serious and could result in a compromised PC, said Thomas Kristensen, chief technical officer for Secunia, a security vendor in Denmark.

Secunia is performing a binary analysis of the old and new versions of Reader to figure out the vulnerabilities. However, that analysis takes one to three days, Kristensen said.

Kristensen said no proof-of-concept code has been seen yet and no attacks have been reported. But people should be especially cautious of PDFs (Portable Document Format), the common file type that Reader opens.

"PDFs are generally highly trusted," Kristensen said. "It's a common format for exchanging information."

Secunia estimates that more than 60 per cent of home PC users have the Reader program, based on data from one of its software products that checks to see if programs have up-to-date patches. Corporate use of Reader is less, around 30 per cent, since many companies use other business applications that can open PDFs, Kristensen said.

Hackers seized on PDFs last year after the disclosure of a protocol handling vulnerability involving Windows. The problem allowed them to create malicious PDF documents that would infect a PC with malicious software if opened.

Adobe officials could not be reached for comment.

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.
