Security Issues in Mozilla
paulius_g writes "SecurityFocus has released a security warning with three problems that affect Mozilla on all platforms. The first issue allows the source of a download to be spoofed, generating a fake URL. This security issue is really easy to replicate: Create a long URL and the downloading box will only display its ending (Mozilla and Firefox). The second issue was created by the way that Mozilla's browsers handle news:// links to newsgroups, hackers can easily create false links and create a buffer overflow (Mozilla 1.7.5 and below, Firefox versions before 1.0). The third exploit affects machines with multiple users. The way that Firefox and Thunderbird store files allows every user to see them and to probably catch the other user's surfing habits (Firefox and Thunderbird). Let's hope that these will be fixed soon!"
==========
All Mozilla users should upgrade to the latest version:
Says the site, implying at least a partial fix is available.
Oh no! Time to switch back to IE.
The tragedy, the inhumanity!!

The way that Firefox and Thunderbird store files allows every user to see them and to probably catch the other user's surfing habits (Firefox and Thunderbird)
Can't the same be said of IE or any program that stores information in %SYSTEMROOM%\Documents and Settings\%USERNAME% ? I mean, it's possible for me to see anyone's "habits" that way, right?

that I can still wipe my Linux box, buy a copy of XP, install, activate, update, reboot, update, reboot, get SP1 & 2, reboot, update, reboot and I'll be able to use Internet Explorer, a safe alternative to....oh wait...
Most viruses are exploits of things MS has patched months earlier. If Firefox becomes mainstream can we count on the average user to update or will an out of date Firefox become nearly as bad as IE?
Gravity is not just a law, it's also a good idea.
This only applies to Windows platforms. Linux and Unix versions maintain all user information in the homedir, preventing access to ordinary users.
The Slashdot article, not security focus. In plain text, at the top, it says these were FIXED in the latest versions.
.9, and Mozilla BEFORE 1.7.5.
They affect Firefox versions BEFORE 1.0, Thunderbird BEFORE
This article was posted by some MS shill who is hoping the because Slashdot is spidered by Google news they will get some mainstream journalism about Firefoxes bugs!
This is TOTAL crap! Let the MS Smear campaign begin!

Why?
Both will have flaws, some major, some minor. And, for me, there seems no real evidence that the Firefox community corrects problems quicker than MS. Both appear to me to fix major problems relatively quickly.
The only real difference is the experience a user gains from using an individual browser. And for me, I personally prefer the FF experience, as I should, having configuring it until it fits like a glove.
"The fact there there are still vulnerabilities should come as a surprise to no one."
Of course not. But, unlike IE, these aren't 'You open a web page and your machine is taken over as a spam zombie' vulnerabilities. They should be fixed, but are less serious than the usual IE bugs... and they'll likely be fixed a lot faster.
Problem One: A String Formatting Issue, URLs should be shown as "http://www.blah.com/.../www.spoof.com/register.ph p" rather than ".../www.spoof.com/register.php" and users should be shot if they can't recognise a valid URL.
Problem Two: Beta Firefox? That's not an issue then. Otherwise, who let a buffer overflow get into the codebase?
Problem Three: Surely this is more of a problem with Windows' Security model? if an OS is used essentially as a single user machine (e.g., 9x) then there is little that can be done between profiles.
If I read TFA correctly, they're fixed already: Mozilla is listed as unaffected in >=1.7.5, Firefox unaffected in >=1.0, and Thunderbird unaffected in >=0.9.
Interestingly, the original bug report came from the Gentoo security people - is there anyone running Gentoo with anything other that the very latest apps?!
This is where the serious fun begins.
The really important thing as far as I'm concerned is the length of time needed to fix newly discovered bugs, not the number, and this is where the open source development model works so much better.
I'm also concerned about those nasty 0-Day vulnerabilites that are out there but we don't know about. The problem with open source is that the code is out there, so its easier to find the bugs. The saving grace is that the code is generally better, and there are usually more white hats looking for the problem than black hats.
I still think FF is safer than IE, but I also think its just as important to be wary of the bugs we don't know about as the ones we do. The same goes for any software product.

Apart from the first issue, of course, which reads:
"The vulnerability has been confirmed in Mozilla 1.7.3 for Linux, Mozilla 1.7.5 for Windows, and Mozilla Firefox 1.0. Other versions may also be affected."
So it's actually just one spoofing vulnerability. It's probably a result of fixing the bug in 0.9.something where an overly long (>4kb, IIRC) URL in the address bar could cause firefox to lock up the x-server.
I have not looked at the latest code base so my response may very well be wrong, however you may want to keep this in mind when making such a statment:
Perhaps one reason is they are not really using C++ to its fullest extent like here as an example.
BSD is designed. Linux is grown. C++ libs
Only the buffer overflow issue has been fixed! This article on the Register should clear things up:
http://www.theregister.co.uk/2005/01/07/mozilla_fl aws/
If you can have buffer over-run vulnerabilities in your C++ app, then you are potentially vulnerable to absolutely anything. The fact that even one exists, even in a beta development, betrays fundamentally flawed coding standards and/or QA procedures. These things should never happen in a C++ app, and the coding techniques to prevent them are trivial.
Easy, tiger. As others have pointed out, most exploits of Windows/IE systems use vulnerabilities that MS patched months ago, and when critical ones do come up, patches usually do appear (with much hype) PDQ.
If you disagree, post your argument. (-1, Overrated) isn't your personal censorship tool for views you don't like.
Click 'cancel' if you are not sure about what you are downloading; Addtionally, you should be able to hover the mouse over a link and see the actual URL in the display bar at the bottom of the window. I do this all the time because I want to be sure where my browser will be connecting when I click anything. Of course, if you go to sites that don't use standard HTML for their links, you could be scammed. Generally speaking, unless you are running IE, downloading a trojan isn't going to be that bad - as long as you don't then try to run it. If you were expecting a picture, or a zip file, and got an executable instead, that could also tip you off. This is probably the worse problem of the three - but nothing to lose sleep over.
The second issue was created by the way that Mozilla's browsers handle news:// links to newsgroups, hackers can easily create false links and create a buffer overflow (Mozilla 1.7.5 and below, Firefox versions before 1.0).
If you aren't using the latest version of the browser - you are wrong. Additionally, who reads news groups anymore? I gave up wading through all the spam and flame wars long ago...
The third exploit affects machines with multiple users. The way that Firefox and Thunderbird store files allows every user to see them and to probably catch the other user's surfing habits (Firefox and Thunderbird). Let's hope that these will be fixed soon! - should do the trick on most unix/linux systems. I can't see this breaking the browser, because presumably it is being run by you as you. This is irrelevant on a Windoze machine because it is not truely multi-user (and I can slap a knoppix disk into your windows machine, reboot linux, and read all your files provided I have physical access anyway - which is how most people 'share' a windows box).
