Mozilla First To Patch Pwn2Own Browser Vulnerability
Constantine the Less writes "Mozilla has released Firefox 3.0.8 to fix a pair of code execution holes that put users of the browser at risk of drive-by download attacks. It includes a fix for one of the flaws exploited during this year's CanSecWest Pwn2Own hacker contest. The update also fixes a separate zero-day flaw disclosed earlier this week on a public exploit site. Both issues are rated 'critical,' Mozilla's highest severity rating."
And good to see Mozilla patching things this quickly.
"City hall" in German is "Rathaus" Kinda explains a few things......
If I want to have Firefox download my exploit, umm, contribution to thousands of users worldwide, could I get such fast service and minimal vetting if I called it a security patch?
If you must moderate, please moderate as irrelevent, not something bad, because I'm sure someone will find this interest
I also thought that open source had a built in Plan B that if a hole was found, anyone could submit a patch and it would get folded in as soon as it was reviewed and approved.
That's funny, this is a story about the Open Source browser being patched before every other browser, and you're not seeing a benefit?
"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
Yeah, and this resulted in them being first to patch. I already have patched version, it downloaded automatically. Even if microsoft patched ie8 today it probably wouldn't update automatically till next patch tuesday. And did closed source helped ms to make more secure browser?
Extreme Programming - Redundant Array of Inexpensive Developers
Seen how insecure web browsers are, what would be a good way to surf under Linux?
I have an account that I use only for GMail and my bank's website (the latter using a physical device answering cryptographic challenge so nobody is abusing that [when wiring money to a new account number, the account number of the recipient itself is part of the cryptographic challenge, there's no MITM, no nothing that can work against that]).
Then I have an account only for browsing. The user owning this account on my machine has user ID 1007.
This user is not even allowed to connect to localhost. I don't want to know. All he can do is surf the web, using iptables like this:
iptables -I OUTPUT -m owner --uid-owner 1007 -j REJECT
iptables -I OUTPUT -m owner --uid-owner 1007 -p tcp --dport 80 -j ACCEPT
iptables -I OUTPUT -m owner --uid-owner 1007 -p tcp --dport 443 -j ACCEPT
iptables -I OUTPUT -m owner --uid-owner 1007 -p udp --dport 53 -j ACCEPT
Are there others simple things I could do to deal with security hazard that these browsers are?
Things I could do about this user's home directory permissions? Disable his SSH? etc.
Basically I think I'd like to have an account that can "do nothing but run Firefox".
Or is there an easy, lightweight (lightweight as in "I don't necessarily want to virtualize a full OS just to run a browser", way to sandbox a browser?
In other words, I consider the "security" of all the browsers to be a bad joke and I regard running a browser basically the same as executing "omgWindozeServer2012Crack.exe" on my machine and I'd like any hint from people who are surfing in a "safer" way.

MS patched this on IE8 on Vista already before it published Mar 19. http://blogs.iss.net/archive/chicksdigIE8.html
XP hasn't been patched yet. Doesn't support DEP, so will be a bit more work.
Is Seamonkey affected by the same bugs? Are the updates ready?
Actually the IE8 exploit used during Pwn2Own contest wouldn't work on the final release of IE8 published one day later on the 19th of March.

The contestants already have next year's winning exploit waiting in the wings. Maybe we should have these contests every month instead of once a year.
What?
How many stories on Slashdot are surprising?
It might not be the best terminology, but it is describing how many days a patch has been available for the vulnerability.
Nerd rage is the funniest rage.
And did closed source helped ms to make more secure browser?
umm, yes.
the person who cracked safari on osx said that ie8 on vista was the toughest to exploit.

But Ubuntu has already reviewed it, and pushed it out through the repositories, marking it as critical. I love open source.

Of having discrete components, and of modular operating systems.
Mozilla isn't integrated into the OS, so they can just fix bugs. IE is "integrated into the OS" which means they can't simply fix bugs, they've got to make sure the rest of the big ball of mud OS continues to work as well.

Well, it wouldn't work on Vista on the final release of IE8, except on Intranet pages. Apparently, it still works on IE8 running under XP, still works on Intranet pages. The underlying vulnerability is still present on IE8 on all platforms, it's just that there's not currently any way to exploit it thanks to DEP and ASLR.
See what sarcasm gets ya?
And that, ladies and gentlemen, is the surprise.
Clicked pie.
Not exactly. They fixed a hole in DEP+ASLR, first reported in August 2008, that made it possible to exploit the IE8 vulnerability (by disabling the functionality the hole was in) - but only for internet sites; intranet sites can still exploit it. The underlying vulnerability is also still there, and there are probably other ways of exploiting it to get code execution.
On the other hand, Firefox on Linux wasn't exploited at all.

Yes, but there wasn't a Linux box. IE 4 on Windows 95 wasn't exploited during the contest either... does that prove anything?
Not up to 24hrs ago. Yesterday I downloaded FF for a client and it was still punting Ver 3.0.7 on Mozillas website.

"Charlie: The NX bit is very powerful.When used properly, it ensures that user-supplied code cannot be executed in the process during exploitation. Researchers (and hackers) have struggled with ways around this protection. ASLR is also very tough to defeat. This is the way the process randomizes the location of code in a process. Between these two hurdles, no one knows how to execute arbitrary code in Firefox or IE 8 in Vista right now. For the record, Leopard has neither of these features, at least implemented effectively. In the exploit I won Pwn2Own with, I knew right where my shellcode was located and I knew it would execute on the heap for me."
That has nothing to do with it being closed source.

I'm not. I can't download the upgrade. I'm running OSX 10.3.9, and Firefox 2.0.0.1. Firefox 3.x requires 10.4.
OSS developers should think about those of us that are still happy with their older software! (or can't upgrade) I'm only 1 major version behind the current Firefox.
I'm not sure if I'm in danger of a drive-by download though. I do remember getting a few "exe" programs downloaded to my HD while visiting some shadier sites. I just laugh, delete it, and move on.
"That's so plausible, I can't believe it!" - Leela
I'm surprised that nobody has mentioned that the XSL issue was reported 5 months ago, and it had a patch ready to go 4 months ago. Why was a critical issue with a two-line patch not fixed immediately? A better question - if the "bad guys" searched bugzilla for unfixed critical issues, how long would it take them to strike gold?
erm that doesn't answer the question, there are some nice technologies in vista* and ie8 can take full advantage of those, eventually FF will be able to use those on vista and still be more secure than IE on xp (something MS has no intention of doing). It DOESN'T have anything to do with it being closed.
IranAir Flight 655 never forget!
What does Fox Mulder's apartment number have to do with this?
It was only immune in the internet zone, due to MS disabling .net controls in that zone. The bug still exists and is fully exploitable in the intranet zone. Also, IE has had a long history of cross-zone-scripting bugs which allow an attacker to run js code in a different protection zone than it really exists in. If you trick IE into thinking your code is in the intranet zone, this vulnerability opens right up.
Why drop support of their previous major version?
'Cause they don't have the manpower and/or money to support the previous major version?
They could at least provide security updates.
I daresay that they did just this for roughly six months after FF 3.0 was released.

Who?
Ignore this signature. By order.
On Vista and Win7, I'd rather use IE as it runs in a sandbox.

Mac OS X is not open-source software. If you can't install Leopard or even Tiger on your PowerPC Mac, try installing a Linux distribution that supports your Mac model. I'm sure they still exist.

For the same reason Microsoft dropped support of Windows 3.1 a long time ago, and in contrast with the reason Microsoft is now trying to drop support for XP.
Obsolete versions waste time and energy. Firefox 2 was supported for some time after Fx 3 came out, but they can't support it indefinitely.
Think of it another way: Mozilla doesn't have to make Fx (well|free as in beer|free as in speech|at all), so don't bitch about it if they decide to do something you don't like, unless you're paying for Fx, which you're not. Note that "Fx" is the correct abbreviation of "Firefox" ("FF" is wrong).
$ make available
Obsolete versions? Firefox 3 is supported in Windows XP, which was released in 2001, but not in Max OS X 10.3, which was released in 2003?
No existe.
Linux on the other hand does have both of those features, and had them long before vista...

Linux is actually way ahead, not sure about mac...
The idea of ASLR was implemented on Linux first, and there are other protections like selinux which go way beyond anything available on other platforms...
Wether people/distributions actually use the features is another matter, but they do exist and do work.

Then why does windows 7 keep warning me about not runnung a antivirus?
I don't have any antivirus programs running on linux and have no problems.
I wonder why the system that is hardest to exploit keeps bugging me about this.
Bah. My dodgy dial-up connection is so painfully slow that I find it amusing to install trojans and watch "hackers" try and control my computer.
"Both issues are rated 'critical,' Mozilla's highest severity rating."
So that's above "ludicrous" then?
There was also that little release of OS X 10.4 a few years back, so that makes OS X 10.3 support similar to supporting Win98 or WinME in terms of previous versions (i.e. two major versions ago). Firefox 3 doesn't support Win98 or WinME either.
Wrong!
