Mozilla Firefox Multiple Vulnerabilities

[Rhino]

Having problems with threads here, so trying this test.

[Rhino]

Post #2.

[Rhino]

Now trying the Firefox advisory link.

http://secunia.com/advisories/30911/

[Rhino]

That works so far. There must be something in that Secunia e-mail I posted that corrupts the threads here. Very weird. Now trying the first part on the Secunia message:

TITLE:
Mozilla Firefox Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA30911

VERIFY ADVISORY:
http://secunia.com/advisories/30911/

CRITICAL:
Highly critical

IMPACT:
Security Bypass, Cross Site Scripting, Spoofing, Exposure of system information, Exposure of sensitive information, DoS, System access

WHERE:
From remote

REVISION:
1.1 originally posted 2008-07-02

SOFTWARE:
Mozilla Firefox 2.0.x
http://secunia.com/product/12434/

DESCRIPTION:
Some vulnerabilities have been reported in Mozilla Firefox, which can be exploited by malicious people to conduct cross-site scripting and spoofing attacks, bypass certain security restrictions, disclose sensitive information, or potentially compromise a user's system.

1) Multiple errors in the layout and JavaScript engines can be exploited to corrupt memory.

2) An error in the handling of unprivileged XUL documents can be exploited to load Chrome scripts from a "fastload" file via
"< script>" elements.

3) An error in the "mozIJSSubScriptLoader.LoadScript()" function can be exploited to bypass XPCNativeWrappers and run arbitrary code with Chrome privileges.

Successful exploitation requires that an add-on using the affected function is installed.

4) An error in the block reflow process can be exploited to cause a crash or potentially execute arbitrary code.

5) An error in the processing of file URLs contained within local directory listings can potentially be exploited to execute malicious JavaScript content.

6) Multiple errors in the implementation of the JavaScript same origin policy can be exploited to execute arbitrary script code in the context of a different domain.

7) Multiple errors in the verification of signed JAR files can be exploited to execute arbitrary JavaScript code with the privileges of the JAR's signer.

8) An error in the implementation of file upload forms can be exploited to upload arbitrary local files to a remote webserver via specially crafted "DOM Range" and "originalTarget" elements.

9) An error in the Java LiveConnect implementation on Mac OS X can be exploited to establish arbitrary socket connections.

10) An uninitialized memory access in the processing of improperly encoded ".properties" files can potentially be exploited to disclose sensitive memory via an add-on using the malformed file.

11) An error in the processing of "Alt Names" provided by "peer"
trusted certificates can be exploited to conduct spoofing attacks.

12) An error in the processing of Windows URL shortcuts can be exploited to run a remote site as a local file.

Successful exploitation requires that the user is tricked into downloading and then opening a malicious Windows URL shortcut.

The vulnerabilities are reported in versions prior to 2.0.0.15.

SOLUTION:
Update to version 2.0.0.15.

So far so good. It may be the script entry in the text of the Secunia alert that is causing all of this.

Now I'll mention a previous post PrezLeefun made saying that it was taking forever to download Firefox. The original post got lost.

[Rhino]

Now I'll try adding Penguin's post.

As I mentioned in a previous post, FF3 does seem a hair pudgy when loading. 10 minutes though is ridiculous.

Have you done the following:

1) Cleared your browser cache. Both Internet Explorer and Firefox
2) Run any spyware removal tools that you have
3) Run whatever anti-virus program you have (AVG is recommended)
4) Cleaned out your Windows temporary folder

So far, there have been no reports of security holes in FF3, nor have any updates/patches been posted to the Mozilla site since it came out. However, loading slow seems to be an issue with a few people that I have run across so far.

Was FF 2.x loading a lot faster before you installed version 3?

[Rhino]

Now adding Prez's last entry.

ff2 was about 2-6 seconds. Depended on how many programs I had running.

[Rhino]

Yep. Looks like that script entry was the problem. Now I'm going to delete the corrupted threads.

[PrezLeefun]

Hi Rhino! hey do you think I should just go back to FF2? Would I loose my bookmarks if I did that?

[Rhino]

Beats me. I know nothing about Firefox.

[Penguin]

Hi Rhino! hey do you think I should just go back to FF2? Would I loose my bookmarks if I did that?

You should not have any trouble with that. But to be on the safe side, go to Organize Bookmarks under the Bookmarks Menu Item and click the Import and Backup menu item and click Backup to keep a copy of them.

[Penguin]

Now I'll try adding Doc's post.

That was actually my post.

As for the Secunia posts, it might be better to just dump the email text into Notepad to strip out any unneeded formatting and then paste from Notepad into the editor.

[Rhino]

That was actually my post.

Fixed.

As for the Secunia posts, it might be better to just dump the email text into Notepad to strip out any unneeded formatting and then paste from Notepad into the editor.

I use the standard editor, so there is no formatting included when I post. It's the same as using Notepad, and that's why I use it. The reason this thing apparently had a problem is because it used the word "script" within html <> symbols, which were also enclosed in quotes. That remained even when using Notepad. There were also several other formatting characters in the text, and those could have been the culprit as well. Apparently the vBulletin software didn't like that.

[ThomasMore]

That's interesting, and I agree with Penguin's comment.

FF2 was always fast-loading, but FF3 was horribly doggy. I am running a completely different browser now (Safari on Apple). Although I miss FF's customization and extensibility, it is supposed to be a memory-hog on Apple's OS. The Mozilla browser for Apple, Camino, left me cold.

[Rhino]

I did some testing. It was the script tag. I fixed it by adding a space before the word "script". The full advisory is now pasted above.

[Penguin]

Makes sense. If VB is using a parser like cbparser it could easily interpret the word "script" as a javascript function and hose up all of the formatting.

[Rhino]

Yeah, but the weird thing is that the problem still existed when I tried the noparse and nocode tags. It only worked when I put the space in. Go figure.

[PrezLeefun]

Thanx Penguin. I'll do that.

[PrezLeefun]

Firefox has become a NIGHTMARE!!!! I uninstalled firefox3 and reinstalled firefox2 and it is still running slow. Its the only program doing this so I dont think it is my computer.

Is there a better web browser that supports stumbleupon and google browser ? And can I import my bookmarks on it?

[Penguin]

Opera is a good little browser, though not highly supported as far as design goes, but it is generally very compliant. (A lot more than IE)

You should be able to import your bookmarks without any trouble. I am not sure if it has the Google toolbar installed by default, though that is probably offered as an add-on.

As for FF, it sounds like something in the registry, maybe vestiges of FF2 are still floating around there, I would highly recommend you get Registry Mechanic. Best registry cleaner out there.

The trial version will only fix some issues. You will need to purchase the full version to have it use all of it's features.
