Adobe Finally Fixes Remote Launch 0-Day
Trailrunner7 sends in this excerpt from Threatpost (Adobe announcement here): "Adobe today shipped a critical Reader/Acrobat patch to cover a total of 17 documented vulnerabilities that expose Windows, Mac, and Unix users to malicious hacker attacks. The update, which affects Adobe Reader/Acrobat 9.3.2 and earlier versions, includes a fix for the outstanding PDF '/Launch' functionality social engineering attack vector that was disclosed by researcher Didier Stevens. As previously reported, Didier created a proof-of-concept PDF file that executes an embedded executable without exploiting any security vulnerabilities. The PDF hack, when combined with clever social engineering techniques, could potentially allow code execution attacks if a user simply opens a rigged PDF file." Relatedly, Brian Krebs blogs about the downsides of Adobe's increasingly Byzantine update process.
Why is every unpatched exploit a 0-day attack? Wouldn't this be more like a multi-month exploit?

First pwnst
What was the impact of this on an (otherwise) fully patched ubuntu machine, running flash, but not acrobat(not installed), in a non-admin account.
I have used my ubuntu machine at home to look at several questionable flash based websites in the last few weeks and want to know if I should format and re-install
Missing from the summary is gsview. It makes a very secure pdf reader that works on windows, although it certainly isn't anything nice to look at. Uses ghostscript for the backend.
Why do people still use pieces of trash like Opera or Firefox or Chrome when Microsoft has shown that IE9 is the most HTML5 compliant browser out there. This paired with IE9's unparalleled record of security means that the only people still using these "alternative browsers" are ideologues or Loonix faggots.
For the 90% of us who don't require all the minutiae of functionality and cruft which Adobe Reader offers, there are options. Obviously Mac folk are covered by Apple's built in Preview, but on Windows, Sumatra PDF is amazing and ridiculously small. It's better than Foxit, in my opinion, for barebones PDF viewing in Windows. Check it out! http://blog.kowalczyk.info/software/sumatrapdf/index.html
after reading the summary and the Brian Krebs blog. I realized that Adobe is shipping a buggy, risky piece of software.
I installed Foxit Reader (minus the Ask.com search bar)..
It seems much snappier, and is significantly smaller.
Thanks for the link. Comparing some documents side by side between Foxit and SumatraPDF, Sumatra rendering has some issues with gamma and images. Text rendering is a little better in Foxit. I can live with the yellow blank starting page, though.
The MSP Installer is also available for those who may use Adobe Reader in silent installs/updates.
Side rant: Why does Adobe still only offer the unpatched versions of Reader on their front page?
Prove it.
Ugh. I just updated on my Mac running 10.6.4. It looks like Adobe is still distributing Reader 9.3.0 as the default distribution package. I had to download/install this version and then apply individual patches for 9.3.1, 9.3.2, and finally 9.3.3. Annoying.
Perhaps it would have been easier had I updated from within Reader?
is it? oh shit
I only saw a proof-of-concept. Have people actually been exploiting this?
Don't thank God, thank a doctor!
This time, whatever these idiots did, the jump from 9.3.0 to 9.3.3 doesn't work at all. It may have something to do with the idiotic "repair adobe pdf viewer" plugin dialogue, which has no title and opens at background, unclickable.
Idiots (hopefully they read) still install Adobe Updater to Utilities but they were lazy to feed it with data so, the dedicated (and working) Updater doesn't work too. Of course, it is still added to launchd per user schedule.
Man how worse you can get? I mean, I am not like those "Use Preview" guys, I actually hate that Quartz shell and I am in process of uninstalling all traces of Acrobat on my entire network for the first time since 1994. You should be glad you run Intel Mac, I actually have 10.4.11 and "Classic" emulating capability. Just yesterday, I launched the Classic/Adobe Reader (5) and was ashamed on behalf of them. That was some real cool, quality software on Mac it seems.
A user uninstalling and giving up Adobe Reader for the first time since 1994, I hope they will lay off Apple/Mac developer team first while going down.
Thank God Apple has some kind of X11 and I actually plan to use kpdf or even xpdf on this Mac Mini which has special needs (connected to 720P).
IMHO they should pray Steve Jobs doesn't have Adobe Reader on his system.

Normally, a "0 day attack" accompanied with some black background, text like html page occuring means
1) Company doesn't take it serious and demonstrates their own case or explains why it is non issue for 99.9% (of course, add to fix list)
2) Company takes it serious (sends out an emergency hotfix which may remove functionality and not very tested but, it works until real thing ships)
As Adobe took it serious but didn't ship a God damn ".bat" file (yes, ms-dos .bat is enough) to remove the component which isn't actually used you got confused.
It is indeed a 0 day but, Adobe isn't a sane company anymore.
I appreciate they probably had some QA to do in order to release this puppy and it took a while, but I loaded Evince, un-installed flash and called it a day. If you can't see it on youtube using their HTML 5 beta then that's a real good time to boot up Linux even if it's just in Xen or Oracle/Sun Virtualbox running on Windows. It works just fine for web browsing and less zero day exploits.
It's been nearly a week since I updated Reader! About time for another download install and unnecessary reboot!
Every single time Reader/Acrobat updates it resets its self as the default viewer. That's completely inappropriate behavior, especially for a 'security update'. (And no, I can't uninstall it. Job requires proofing PDF in Reader just like all my poor clients.)
I saw/overheard this in a bar recently (seriously):
Girl: So where do you work?
Guy: Adobe.
Girl: Oh yeah, you're the guys always asking me to update and reboot. *walks away*
When using ExitWindowsEx() at the end of your patch install, don't use the damned EWX_FORCE flag. It doesn't even give users enough time to respond to the "Save? Yes/No/Cancel" dialogs popping-up before the applications are kill -9'd and users lose all their unsaved data.
It's about time, however there are still a few more exploits that have not been addressed....until these have been fixed too, i am sticking to fox it pdf reader....
Thanks for bringing up Sumatra - do you happen to know any good pdf viewer for windows 98? (I tried Foxit 2.x but it's buggy as hell in win98).
