Firefox 1.5 Exploit Code in the Wild
By Nate Mook | Published December 8, 2005, 1:31 PM
Proof of concept exploit code for an unpatched security flaw in the newly released Firefox 1.5 was publicly posted Wednesday by Packetstorm Security. The problem involves Firefox's history database, which cannot handle extremely long page topics. A malicious Web page could cause a buffer overflow that crashes Firefox each time it is started.
The only way to fix the problem is to manually delete the history.dat file before Firefox is started. "This vulnerability has been tested and does work, and no known patches are available at this time," wrote John Bambenek on the SANS Internet Storm Center. "Presumably, if the topic was more tightly crafted than in the proof-of-concept code, a more malicious attack could be crafted that would install malware on the machine."
"Update 2: The official response from the folks at mozilla.org can be found here(http://www.mozilla.org/security/history-title.html). Their results match our testing, that we were able to make it take a long time for Firefox to start, but were not able to make it crash. Further, there doesn't seem to be any credible evidence at this time that this could be exploited to execute arbitrary code."

|This actually not a Firefox specific bug, but a long known Mozilla problem.
It's common knowledge among the mozilla hackers that the history database format (as well as address book in mozilla mail) named "Mork" was coded by a guy who was totally out of it.
The format is impossible to understand, the code is hard as hell to maintain, and noone yet dared replacing it with something better, even though there are plans to use a unified storage engine less bug-prone (http://wiki.mozilla.org/Mozilla2:Unified_Storage)

All this does is cause Firefox to load much slower. So let's all come to our senses here, shall we?

The Mozilla Foundation will release a patch for this exploit. They will release a patch for any exploit much faster then Microsoft ever will.
Nothing is completely safe, but at least we can rest easier knowing that the programmers of Firefox will resolve the issue promptly.

What are u talkin 'bout? Safety? Does safety not depends on market share? Oh, sorry. It's in ethic written, answers first. I use Ff, who said it's safer, when all the safety comes from unsupporting activex and virtualizing secure zones, [wo]man? Let's begin from crashes when msdos came, stud'stuff for a while before talking. Unix are crashing easy, but many homics uses winds, so politics are easy at all. Give homes Ff to use more, holes will follow.

When you write literally millions of lines of code you are going to have vulnerabililities no matter what company you are.
Most of the time they don't know of an exploit until it happens.

|For me, it has nothing to do with bashing Microsoft, though their track record with security is less than stellar. I personally think they deserve it, because they make choices based on sales and marketing instead of what makes for the best software. But that is beside the point.
Firefox generally *is* more secure. Fewer exploits, and the ones that have been found tend to be much less severe.
I'm no fanboy. I agree that software fanboys are truly irritating. But implying that you're not better off running Firefox than IE is irresponsible.

|Nobody, at least out of the people who have any idea what they're talking about, has claimed that Firefox never has flaws. We simply argue that when a critical flaw comes to their attention, they fix it in a matter of days or weeks, instead of waiting years to fix it like Microsoft does.
Score: 0
|I'll admit, I've bashed MS before but only when they truly deserved it. However, when I started using Firefox, I did so knowing full well that it would have its own set of security flaws to go along with it. I mainly began using it because of it's extensibility, simply because it allows me to choose the features that are best suited to what I need. I don't get stuck with a bunch of stuff I never use, such is the case with Opera (which for some reason I find to be a bit clunky). In the case of IE, there's a serious lack of features that are available to me through Firefox. So yea, I'm not a FF user because I believe it's bullet proof because any fool should know that the very idea of a impervious browser is ludicrous.
Score: 0
|Exactly my point, I am not saying IE is better than any of the other browsers only that to bash any of these companies is crazy.
You can't plug a security hole until you know you have one.
I also agree MS does take to long to address some issues.
No reputable company is going to invest tens of millions of dollars to intentionally put out a bad product that could, make them fall on their face. There's just to much at stake. (Oh this includes every reputable company but Sony they're just stupid!)
Now I am not saying some might not rush things to market in hopes to fix it later. (which is stupid)

|Obviously a well-reasoned comment. How long did it take you to get the wording just-so?
However, you're correct - all browsers do have their flaws and I think it would be unreasonable to assume a browser never has any flaws discovered. The real proof will be in the time it takes for a fix to appear.

|This should be a good first public test for the new auto-update feature in Firefox.
Meanwhile, it's worth noting that although this vulnerabilility has come to light
within a fortnight of the newest major upgrade for Firefox, it's really not that
big a deal, seeing as Secunia have rated the bug as "Not critical".
It's also worth noting that, aside from this relatively minor security issue that
has arisen in Firefox, one of the current security bugs in IE, has been there
for about six months now, and is rated as "Extremely Critical" by Secunia.
Is there a patch for it? Nope. Nada. Zilch. Zero. Not a sausage!

I agree that it's a security flaw. I never claimed it not to be, I simply had a problem with the headline blowing it out of proportion...of course, my disagreement with that headline has now also been blown out of proportion, so I guess all is good.
:P
I suppose it comes down to a difference of definition. To me, ITW means it's out there, on warez sites, waiting to tear your heart out, stomp on it, date your girlfriend, and steal your Cap'n Crunch. Under that assumption, the headline is dead wrong.
Kinda gives anyone who thinks ITW means the same as I do the wrong impression, eh?

|DOH!
No browser will ever be 100% safe. Just like Windows OS and most other programs.
At least the competition will help promote more innovation within browsers.
IE would still be using windowed browsing if Firefox (and others) hadn't started using tabs.
Every program has competitors, they help increase innovation, new features and overall safety. It's easier to attack people's computer if they all use the same program.
At least if there's 2 browsers, you've got a smaller chance of being targetted. Even less if there's more competition!
Personally my main problem is with websites installing spyware and the like, for now Firefox works best for me.
I also like all the different extensions (weather, adblock, etc.) I have installed.
It's each to his own really, you should choose which one works best for you.
None will ever be 100% truly safe. Just enjoy the results of a little healthy competition!!

|Actually I think that's the very nature of open source, so your sarcasm is kind of off-base. The whole idea behind open source is to put the source code out there so developers/testers/etc. can help find and fix bugs and make improvements. Most people that support open source aren't going to claim there are no bugs.
On the other side though, for Firefox users (who I am one of) who claim it has no flaws and is air tight (who I am NOT one of) are a little over zealous. Everything has its flaws... it just comes down to who decides to capitalize on them.

|Data Execution isn't going to solve the problem of poorly programmed or written software. It just prevents known program hacks to run, and you can set a limit on software that will run on the machine.
Have you actually setup Data Execution? There is a BIOS setting, a BIOS update, additional software to install in the OS, changing a registry setting, and then monitoring the list of software that is ALLOWED to run. Its more work to use than its worth. Unless they find a much easier and better way to admister it, it will NEVER get noticed. If you miss an add-on, or a program, you are screwed. Some suites, like office, you have to INCLUDE "ALL" the applictions in the suite.
You can't choose "Microsoft Office" as an allowable package, you have to choose, word, outlook, excel, access, paint, mstoolbar, open document, save document, and each and every excutable.. Yeah, Data Execution is a GREAT idea..
