New Adobe Flash Vulnerabilities Being Actively Exploited On Windows and OS X
Orome1 writes "Adobe has pushed out an emergency Flash update that solves two critical vulnerabilities (CVE-2013-0633 and CVE-2013-0634) that are being actively exploited to target Windows and OS X users, and is urging users to implement it as soon as possible. According to a security bulletin released on Thursday, the OS X exploit targets Flash Player in Firefox or Safari via malicious Flash content hosted on websites, while Windows users are targeted with Microsoft Word documents delivered as an email attachments which contain malicious Flash content. Adobe has also announced its intention of adding new protections against malicious Flash content embedded in Microsoft Office documents to its next feature release of Flash Player."
I know many will rush to disagree with me but Flash cannot die soon enough...
>Who in their right mind opens a Word doc from and unknown source
The idiot secretary in the next office over, or the next floor down.
Then the payload mines her email addresses and sends you "Minutes from meeting" or some similar crap. So now instead of having an email from an unknown person you get an email from someone you'd expect to get word documents from. Hopefully you are in a company that has decent A/V on incoming mail, most small businesses don't.
Yep. HTML 5 can offer hardware acceleration on pretty much any mobile device.
The reason for flash was that Java was an ugly POS and people did not want to wiat a full minute for their ugly applets to load while flash was all nice and pretty and loaded instantly.
Flash also exists because of IE. Old IE I may add as IE 9 and IE 10 got their act together and support the HTML 5 video tags. When IE 10 comes out for Windows 7 and XP goes EOL we will see a shift in websites catering to HTML 5 users making flash obsolete for all but the conservative businesses.

Can you tell us what that is?
For me, Flash has never provided anything of value -- just ads and badly written web sites is my opinion of it. I think Flash is crap.

There's a reason Flash is the world's most popular online multimedia platform.
Yes. DRM.
Some time ago, after the last round of Flash exploits, I de-installed it and resolved to live without it.
There are glitches: I can't get most video content, and Flash-only sites are inaccessible. However, this ended up being not a big issue.
One reason for this is that many YouTube videos play in HTML5 on Firefox. (If you find a video you can't play, try embedding it; this sometimes produces a workable version.)
Overall, the playback on HTML5 is better than Flash. There are fewer random slowdowns and stall-outs. On the downside, not every video is in HTML5.
The most amazing this is that browser crashes have dropped to near zero, either one or zero during this time. Most of what I thought was FF and Opera being buggy was in fact Flash being buggy.
There's not yet enough content switched to HTML5 from Flash to navigate everything, but during my 6 months without Flash, I've noticed that more firms are going away from the Flash-only navigation school of design.
YMMV. For me, life without Flash has been better, although I do miss out on some things.

Probably because there is not much you can do to fix a fundamentally bad idea. Think of it like all the various attempts to make smoking 'healthy' at the end of day intentionally sucking combustion gases into your lungs just is not good for you, no matter how low tar, free of synthetic chemicals etc you make it.
What does flash do? It executes code from unknown origin on your machine. That has never been a good idea; even if in some cases you can't get around needing to do it. Flash has more problems though it can't be fully sandbox'ed without breaking all those old apps, it needs to be able to do things like read files, open sockets connections, etc.

People use Word documents to send freaking pictures around, because they don't know they can paste into Paint. They don't know how to send weblinks either, so they paste it into Word and send it on.
A successful API design takes a mixture of software design and pedagogy.
Windows users are targeted with Microsoft Word documents delivered as an email attachments which contain malicious Flash content
Why?
Probably because of Windows sandboxing Flash through low-integrity mode. Even if you get to exploit a Flash vulnerability and execute your shell code on Windows, the code is still severely restricted in what it can do. Code executing inside of a low-integrity process can still not infect a system as write-ups (writing or interacting with a higher integrity object/process) are denied.
They could as easily infect you with a macro. Who in their right mind opens a Word doc from and unknown source, especially when Windows warns you when you start to open a word doc in Outlook (we use Outlook at work).
No, infecting with a Macro is more difficult since the last several versions of Word. Word will not automatically run macros and also has an internet-origin policy whereby documents received through Outlook or other email clients or downloaded using a browser is tainted with the "internet zone". You have to dismiss several warnings to run macros from such a document. But if Word will run Flash content (show the animation) and a vulnerability can be exploited, shell code can run as a user.
That is, until Word 2010 which *also* runs in low-integrity when viewing content tainted with the internet zone. Since Word 2010 the shell code will still be confined to the low-integrity sandbox.

You're entitled to your opinion.
But Flash remains a remarkably viable platform with mature development tools for animation, video and games. Amanita Design comes vividly to mind with games like Samorost, Machinarium, and Botanicula.
Animation in adds and badly designed websites don't go away simply because their developers have migrated to HTML5.
We see here how the Windows platform has been battle hardened to the point where the attackers have to resort to lower-yield secondary attacks. Head-on attacking Flash on Windows does not get the attacker very far because of the security advancements such as Mandatory Integrity Control (MIC). That's why the attackers try to exploit it in contexts where MIC does not prevent system infection, such as through older versions of Microsoft Word through emails.
OS X is still wide open to such head-on attacks when a vulnerability exists, especially Firefox because Mozilla has steadfastly refused to put in place a proper sandboxing barrier. Even Safari has some sandboxing in the latest version of OS X.
Firefox not. A vulnerability in Firefox or one of its plugins means significant risk of successful exploits.
Flash on Windows executes in a low-integrity process. Even if a Flash vulnerability is exploitable and shellcode gets to execute in the Flash host process, it still cannot write anywhere or interact with higher integrity objects because of mandatory integrity control (MIC) which was introduced with Vista.
The upshot: Attackers have to try secondary routes on Windows where the conversion rates are much, much lower. And this specific attack vector will not work on Word (or other Office applications) since Word 2010. Since the 2010 versions, internet downloaded documents are also opened in low-integrity mode, meaning that even here the shellcode would be similarly restricted.

And replace it with what? The atrocity also known as HTML5 which is not write once run anywhere, is an absolute bear to code and despite the hype is nowhere near suitable for gaming yet?
It's true that for this one particular use-case, Flash may still have an edge against open technologies. But 99% of the Flash on the web is either ads or videos. We don't want to see the ads anyway, and HTML5 makes embedding videos without Flash in a standards-compliant fashion relatively easy. And remember, if your site relies upon Flash, no one with an iDevice will be able to use it correctly. And that's not going to change. In contrast, HTML5 videos work fine on both desktop browsers and portable devices.
If the only thing Flash is good for is some types of online gaming, then many users don't need it at all, and for those who do, it should be set by default to use a whitelist and only permit the plugin to be invoked on domains that are specifically authorized by the user.
Good for you... but it turns out that a fair number of the most popular websites on the entire WWW play videos, typically in Flash, and they are watched by people of all ages (perhaps more among the younger set, but certainly not exclusively). Quite a few sites (perhaps not individually the most popular, but a massively common *class* of site) also serve lots of Flash video, although for legal reasons they are only supposed to be watched by adults. People also like to watch videos of events they couldn't make it to and listen to streaming music, both of which are common uses of Flash. You can do web-based video chat or even videoconferencing using Flash (Google Talk can do this, for example).
I don't like Flash, and I certainly don't trust it; I keep it tightly curtailed where it's installed at all. However, it's definitely useful in some cases. HTML5 is catching up, but not fast.
