Adobe patches critical vulnerabilities in Flash Player, Shockwave

An exploit targets one of the vulnerabilities by using Flash content embedded in Microsoft Word documents, Adobe warns

Adobe patched several vulnerabilities in its Flash Player and Shockwave Player on Tuesday, including one for which an exploit is already available.

"Adobe is aware of reports that an exploit designed to trick the user into opening a Microsoft Word document with malicious Flash (.swf) content exists for CVE-2013-5331," the company said in a security advisory.

That CVE (Common Vulnerabilities and Exposures) ID refers to a type confusion vulnerability fixed in the new version of Flash Player. A memory corruption flaw tracked as CVE-2013-5332 was also fixed. If exploited successfully, both vulnerabilities can lead to arbitrary code execution allowing attackers to take control of the affected systems.

Some mitigation for this type of exploit exists since Flash 11.6, which introduced a click-to-play feature that requires users to confirm the playback of Flash content embedded in documents when opened in Microsoft Office versions older than Office 2010.

Tuesday's update, though, moved the Windows and Macintosh versions of Flash Player to version 11.9.900.170, and the Linux version to 11.2.202.332. The Flash Player versions bundled with Google Chrome, Internet Explorer 10 and Internet Explorer 11 will automatically be updated through those browsers' update mechanisms.

The two Flash Player vulnerabilities were also fixed in Adobe AIR, a runtime for rich Internet applications that has Flash support. The patches are included in Adobe AIR version 3.9.0.1380 for Windows, Mac and Android.

Adobe Shockwave Player version 12.0.7.148 for Windows and Mac was released Tuesday to resolve two different memory corruption vulnerabilities -- CVE-2013-5333 and CVE-2013-5334 -- that could lead to arbitrary code execution. Shockwave Player is not as widespread as Flash Player, but it is installed on over 450 million desktop computers, according to Adobe, which makes it a potential target for attackers.

Since there are reports of an existing exploit for one of the two Flash vulnerabilities, "our recommendation is to include the Flash release in your 'patch urgently' category," Wolfgang Kandek, CTO of vulnerability management firm Qualys, said in a blog post.

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.
