Adobe warns of new Flash Player zero-day attack

Hackers are embedding malicious Flash Player files in Microsoft Word documents to launch targeted attacks against select businesses, according to a warning from Adobe.

This latest Flash Player zero-day attack comes just weeks after EMC’s RSA Division was hit with a malware attack that used a rigged Flash (.swf) file embedded in a Microsoft Excel document.

In both cases, the attacks are being used to steal corporate secrets.

Here’s the gist of the latest Flash Player zero-day:

A critical vulnerability exists in Flash Player 10.2.153.1 and earlier versions (Adobe Flash Player 10.2.154.25 and earlier for Chrome users) for Windows, Macintosh, Linux and Solaris, Adobe Flash Player 10.2.156.12 and earlier versions for Android, and the Authplay.dll component that ships with Adobe Reader and Acrobat X (10.0.2) and earlier 10.x and 9.x versions for Windows and Macintosh operating systems.

This vulnerability (CVE-2011-0611) could cause a crash and potentially allow an attacker to take control of the affected system. There are reports that this vulnerability is being exploited in the wild in targeted attacks via a Flash (.swf) file embedded in a Microsoft Word (.doc) file delivered as an email attachment, targeting the Windows platform. At this time, Adobe is not aware of any attacks via PDF targeting Adobe Reader and Acrobat. Adobe Reader X Protected Mode mitigations would prevent an exploit of this kind from executing.

Adobe says it is in the process of finalizing a schedule for delivering patches for Flash Player 10.2.x and earlier versions for Windows, Macintosh, Linux, Solaris and Android, Adobe Acrobat X (10.0.2) and earlier 10.x and 9.x versions for Windows and Macintosh, Adobe Reader X (10.0.2) for Macintosh, and Adobe Reader 9.4.3 and earlier 9.x versions for Windows and Macintosh.

Because Adobe Reader X Protected Mode would prevent an exploit of this kind from executing, Adobe plans to fix this issue in Adobe Reader X for Windows with the next quarterly security update for Adobe Reader, currently scheduled for June 14, 2011.

AFFECTED SOFTWARE VERSIONS

  • Adobe Flash Player 10.2.153.1 and earlier versions for Windows, Macintosh, Linux and Solaris operating systems
  • Adobe Flash Player 10.2.154.25 and earlier for Chrome users
  • Adobe Flash Player 10.2.156.12 and earlier for Android
  • The Authplay.dll component that ships with Adobe Reader and Acrobat X (10.0.2) and earlier 10.x and 9.x versions for Windows and Macintosh operating systems

NOTE: Adobe Reader 9.x for UNIX, Adobe Reader for Android, and Adobe Reader and Acrobat 8.x are not affected by this issue.

Yet another example where Microsoft's EMET is likely to safegaurd you:

Just like in a previous zero day situation:

Too bad the RSA doesn't use Microsoft's EMET as they were recently hacked.

Is there a reason Flash content can be embedded in office files? I can't see there being a good reason for it.

Now I wonder if some SOB can do this with one of those flash ads that are the curse of downloading so many web pages these days. I swear some of those pages are a terabyte with all the damn flash ads on them.

Firefox or Chrome with Flashblock defaulted to deny all. All you have to do is click a button if you really want the content is the current best method of preventive measures against total Flash in the Pan Meltdown.

But doesn't save you from Flash embedded in Office documents. We now need a Microsoft Office FlashBlock plugin.

Three things. Firefox, NoScript, Flashblock.

Things like Adblock don't hurt either.

Ya know, Adobe and Microsoft both are guilty of releasing software "constantly" that leads to this. Maybe they should slow down a bit ehh? As a web developer, I spend more time patching than coding and I need to code around a lot of the garbage Adobe puts out. In my opinion, they need to spin off what they bought from Macromedia to someone who cares.

Yep, the one that supposedly needs a downloader to help move a tiny 2MB file, said purpose of the downloader really to display ads for yet more Adobe muck. And then requires you to check a stupid box to acknowledge some behind the scenes EULA that demands you don't reverse engineer or decompile this commercial security breach to steal its worthless intellectual property.

I would be real careful with anything created w/ MS Office, or compatible with MS Office. Since similar show up in Word & Excel, & I use Ubuntu, I think I'll open as a text file, after scanning closely. I'm not paranoid, I KNOW they're out to get me.

Apple Is Such A Flash Hater
m0o0o0o0o 11th Apr 2011
Wait - wasn't there something in some lame talk Jobs gave about Flash being a disaster and a security nightmare so it was being banned from iOS? What an idiot. Clearly Apple is just hating on Adobe

@m0o0o0o0o And you are an idiot... this has NOTHING to do with Apple - Jobs saw the truth that Flash sucks out loud, this is just even more proof of that. This has nothing to do with hate for Adobe and everything to do with how badly Flash sucks out loud. If Flash is so wonderful tell me why is it that the number one downloaded browser plug in/ extension is a Flash Blocker?

Troll elsewhere Adobe Shill.

That's not quite true for Linux, at least on Suse, you use what is in usr/lib(lib64)/browser-plugins. I'm currently using the 64bit square versions which works very well. In windows you can make chrome use a different version of flash:

'autorun' feature
nigelrf 11th Apr 2011
@wizardjr, shawkins & boomslang: Agreed. If anyone is serious about ending such issues regarding many such scenarios much less this one, the browser makers and MS should build-in the default block option for ALL applications that run software with potential for abuse. As an alternative for essential operations using flash, they should utilize another means of execution.

Maybe bad for advertisers, but worse for consumers of advertising... or maybe it good to keep the consumer more beholden to hardware and software vendors than needed.

@MrElectrifyer The solution to insecurity in a plugin is not another plugin.

Microsoft are fully committed to HTML5, while Silverlight will be around for quite a while, I'm sure Microsoft won't be pushing it to the detriment of HTML5.

Save us from confusion-creep ...
PassingWind Updated - 12th Apr 2011
It used to be simple. You chose an application appropriate to what you want to do. Working with words - word processor. Working with numbers - calculator or spreadsheet depending on how many numbers and how often you do the calculation(s). Working on photographic images - an image processor. Making an image - a painting program. Creating a drawing - a drawing program.

Then we wanted to print things - OK until we want to print words and pictures. Then the word processor became a word-and-picture processor.

Then we went multi-media, using sound and video. At that stage it is logically "bye-bye paper" - except that we still want to take away printed copies of what we experience. Duhhh. And the word processor suddenly becomes the universal tool. There is no logical reason why the drawing program or the spreadsheet could not have become the universal tool, but the word processor was and is where everybody starts, so that is where things logically migrated to.

But hold on - market complexity is what makes money. Confused customers are vulnerable, and that means exploitable, so let's make a better word processor that can do other things as well, a better spreadsheet that can do other things as well, and so on ....

And make an ecosystem with so much confusion in it that nobody knows what anything is for anymore - except that anything can be used for everything, and everything can be used for anything. And let's have lots of different anythings. In this ecosystem anybody can perpetrate any mischief because as the confusion spreads it becomes impossible for anybody to police anything; when anything can do anything there are no rules to police.

For heavens sake will somebody put one copy of each bit of functionality into a single anythingprocessor so we only have one UI to learn, one way of invoking each primitive element, and no need for any more upgrades except to add new functionalities to this one program. In this way, only one environment has to be made secure.

The lead has to come from the Open Source community - putting pressure on the Software-as-a-licence-to-exploit-confusion (SAALTEC) community to compete with its standards-based user friendliness. The hard work has already been done - several times over and in several different ways. All we need to do is to put the best examples of each feature into a single simple framework.

Then give this reader-browser-editer-creater a new name. Call it an opener, and make web2.0, the cloud and all the other buzz word developments invisible to anybody using an opener.

And specify the universal plug-in interface for any opener.
IF youTube stopped using Flash, I'd delete it everywhere!
