21 Firefox vulnerabilities reported today


Recommended Posts

and neither did neowin.

The headline "Firefox Update Contains 21 Security Fixes" indeed _does_ imply that the most recently released update (to 1.5.0.2) contained 21 security fixes. Which it doesn't.
Late last week, the Mozilla foundation rolled out an update for Firefox, a web browser. Whilst they somewhat coyly alluded to a number of fixes in the version, it wasn't immediately clear the scale of fixes contained in the update. In case you were in any doubt, the number is 21
This STATES that the update contained 21 security fixes, which is TOTALLY wrong.

Otherwise, next time MS releases an IE patch, why not compare it to an unpatched IE5 and say "IE Update contains 200 security fixes!"

wow ... look at the firefox fanboys .. "Yeah most of them already upgraded" ... that doesn't mean that there weren't there. People are always talking **** about IE. Yeah IE had it's problems but hey it was one of the first webbrowsers on the Windows platform. And all you fanboys should also have a look at the latest IE6 and also the IE7 beta2. IE6 on XP SP2 + anti-virus is almost unhackable. I can safely browse the most spyware loaded website in IE6.0 without one infection.

So saying that Firefox is secure is just plain bull. The idiots that use it are just too stupid to admit that the browser isn't perfect. It's slow as hell ... hell even Safari is faster.

Thanks Secunia ... you made my day :)

You come out and call people fan boys yet come across as an anti-Fx fanboy yourself. What's so hard about not being so biased towards any browser? Some people....

And, for the record, I don't think anyone in this thread has claimed Fx to be perfect or better than IE.

How did secunia make your day? By posting vulnerabilities that HAVE ALREADY BEEN PATCHED?

I guess we can't say that X or Y is the most secure browser. If IE is (or was) insecure, it is because it IS the main target, beeing the most used browser. And people are not wrong when they say that IE sucked, because Microsoft had simply stopped working on IE. They began to care when Firefox was released, and they released SP2.

Right now, with Firefox getting more and more users, vulnerabilities are to be expected. I think it's REALLY possitive that they get patched fastly.

You can't compare vulnerabilities of open and closed source applications. Closed source programs can be really shoddily made and have thousands of exploits, but they are harder to find since you don't have the source available to the general public. Furthemore, you have people finding 'exploits' which are totally ridiculous (probably most of the listed ones can't be exploited unless you have someone making an extension which you install and they know how to find a location in memory which to overwrite (which is close to impossible)).

Another useful thing with open source programs is that anybody can write a patch to fix it, and it doesn't take 3+ months to do so (compatability testing included)

Another great reason to move to Opera, the fastest, most secure browser...Period.

Why bring Opera name into this thread, it has nothing to do with Firefox . and as for Opera being the most secure browser i doubt that,no browser is. if Opera gets popluar just as Firefox and IE, it going has these problems as well.

Description:

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

1) An error exists where JavaScript can be injected into another page, which is currently loading. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an arbitrary site.

2) An error in the garbage collection in the JavaScript engine can be exploited to cause a memory corruption.

Successful exploitation may allow execution of arbitrary code.

3) A boundary error in the CSS border rendering implementation may be exploited to write past the end of an array.

4) An integer overflow in the handling of overly long regular expressions in JavaScript may be exploited to execute arbitrary JavaScript bytecode.

5) Two errors in the handling of "-moz-grid" and "-moz-grid-group" display styles may be exploited to execute arbitrary code.

6) An error in the "InstallTrigger.install()" method can be exploited to cause a memory corruption.

7) An unspecified error can be exploited to spoof the secure lock icon and the address bar by changing the location of a pop-up window in certain situations.

Successful exploitation requires that the "Entering secure site" dialog has been enabled (not enabled by default).

8) It is possible to trick users into downloading malicious files via the "Save image as..." menu option.

9) A JavaScript function created via an "eval()" call associated with a method of an XBL binding may be compiled with incorrect privileges. This can be exploited to execute arbitrary code.

10) An error where the "Object.watch()" method exposes the internal "clone parent" function object can be exploited to execute arbitrary JavaScript code with escalated privileges.

Successful exploitation allows execution of arbitrary code.

11) An error in the protection of the compilation scope of built-in privileged XBL bindings can be exploited to execute arbitrary JavaScript code with escalated privileges.

Successful exploitation allows execution of arbitrary code.

12) An unspecified error can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an arbitrary site via the window.controllers array.

13) An error in the processing of a certain sequence of HTML tags can be exploited to cause a memory corruption.

Successful exploitation allows execution of arbitrary code.

14) An error in the "valueOf.call()" and "valueOf.apply()" methods can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an arbitrary site.

15) Some errors in the DHTML implementation can be exploited to cause a memory corruption.

Successful exploitation may allow execution of arbitrary code.

16) An integer overflow error in the processing of the CSS letter-spacing property can be exploited to cause a heap-based buffer overflow.

Successful exploitation allows execution of arbitrary code.

17) An error in the handling of file upload controls can be exploited to upload arbitrary files from a user's system by e.g. dynamically changing a text input box to a file upload control.

18) An unspecified error in the "crypto.generateCRMFRequest()" method can be exploited to execute arbitrary code.

19) An error in the handling of scripts in XBL controls can be exploited to gain chrome privileges via the "Print Preview" functionality.

20) An error in a security check in the "js_ValueToFunctionObject()" method can be exploited to execute arbitrary code via "setTimeout()" and "ForEach".

21) An error in the interaction between XUL content windows and the history mechanism can be exploited to trick users into interacting with a browser user interface which is not visible.

Successful exploitation may allow execution of arbitrary code.

Solution:

Update to versions 1.0.8 or 1.5.0.2.

:laugh:

And all you fanboys should also have a look at the latest IE6 and also the IE7 beta2. IE6 on XP SP2 + anti-virus is almost unhackable. I can safely browse the most spyware loaded website in IE6.0 without one infection.

Interesting - you've really enlightened me. So, ah, what's your IP address? I'm just... curious.... :whistle:

:laugh:

Will people please stop quoting the entire (very long) original post and then replying with a useless one-line response?

I'd just like to point out how none of these vulnerabilities were exploited. That's still one thing Firefox has over IE.

Do you have any proof that none were exploited? I mean, there were and still are 21 exploits (if you're not using .2) and its hard to believe no one exploited not a single one of those vulnerabilities.

Thanks Secunia ... you made my day :)

rofl :D u made me laugh! :laugh:

IE6 it not close to unhackable, almost everything is hackable, including firefox, they just havnt been found/designed yet.

and the spyware thing...since using firefox i get like 3 tracking cookies every now and then, when i used IE, i would get spyware al the time.

To clear some things up because reading a few of your guys comments and its clear you donno what your talking about.

Its like this. I report a vulnerbility throught mozilla's bugzilla and mark it as security. Mozilla fixes problem. New release. Mozilla released the info to secunia and public after a few days after release.

or its like this joe blow reports to secunia a problem and secunia posts it right away.

so this happend with these 21, people reported to mozilla or devs found them and not secunia and patches were made and a release was done.

and the spyware thing...since using firefox i get like 3 tracking cookies every now and then, when i used IE, i would get spyware al the time.

cookies are cookies, you block them or you don't. there should be no difference between ff, opera and ie on that account. at least that's what i think

Another great reason to move to Opera, the fastest, most secure browser...Period.

Nobody cares, mate..And anyway, you have nothing to prove it is more secure..

In fact, it could be so insecure that they have decided not to inform Secunia of the vulnerabilities..

@Raven or firefox 1.0, where does IE come in here?

It's interesting how these vulnerabilities are mentioned after an updated version is released. It's been a while before .1 was released, and those vulnerabilities were there at the time too. But once again, competition is good, wonder what ms thinks about these fixes.

Well IMO I think it's quite good, because it shows something is actually being done..

And yeh, great for competition.. :shifty:

What the heck are you on about?? Really..

Yeh, us 'fanboys' have upgraded..good for us if we have the safety of our PC in our best interests, and don't want the vulnerabilitys to be exploited.

And guess what, smartass...my firefox upgraded for me on it's own accord! :p

"IE6 + SP2 + Anti-virus" is unhackable..Stop talking out of your ass..

How can AV's stop you from being hacked..I think you might be talking about a firewall there ;)

And how do you know that since you have SP2 there are no vulnerability's in IE..

OF COURSE THERE ARE..nothing is perfect..Believe me when I say the new IE7 is far from perfect..

Wake up to the light...might clear those misconceptions your mind seems to be filled with ;)

Guess what..nobody said Firefox is perfectly secure..But let me tell you this..Firefox is secure enough for me already, and with Mozilla releasing patches in such a short time I don't think I am very worried about being 'hacked'..

And another thing.. It looks to me like YOU'RE the idiot judging by your post..Didn't I just admit Firefox wasn't perfect? And believe me..only an idiot like you could make Firefox slow :laugh:

And what exactly are you thanking Secunia for? Pointing out what a great job Mozilla are doing at patching vulnerabilities? Wow, that's one thing I must agree with you on..

Great to see we finally have an understanding.. :cool:

I'd just like to point out how none of these vulnerabilities were exploited. That's still one thing Firefox has over IE.

Tell that to the poser I quoted above :rolleyes:

And at the actual article..Good job Mozilla for patching everything so fast, and Secunia for helping bring that information to the eye of the public.. :)

Do you have any proof that none were exploited? I mean, there were and still are 21 exploits (if you're not using .2) and its hard to believe no one exploited not a single one of those vulnerabilities.

There are only 7 in 1.5.0.1 (18 in 1.0.7)

An update to 1.5.1.x would indicate an API changed that extension(s) use. So if firefox was bumped to 1.5.1.x then all your existing extensions would stop working until their <maxversion> was bumped to 1.5.1.* (Currently they should all be set to 1.5.0.*)

Since no API changes have been made, only security/stability fixes, then bumping 1.5.0.1 to 1.5.0.2 was the right thing to do; all extensions still work as they did before.

Well one can blame Secunia for making people assume right off the bat that it was referring to 1.5.0.2 with all 21 fixes.

http://www.mozilla.org/projects/security/k...rabilities.html

Most of those advisories don't affect 1.5.0.1. The ones at the start say they affect Firefox before 1.5.0.2, the rest say they affect Firefox before 1.5 when in fact only 7 fixes are featured in 1.5.0.2 compared to a whopping 18 in 1.0.8.

By the way for Firefox 1.0.8 unlike what they planned in the past they decided that 1.0.8 will be the last of the old Aviary1.0.1 Branch releases unless something comes up to warrant a 1.0.9

    • Microsoft launches Godot Sample to streamline Xbox PC game development on the engine by Pulasthi Ariyasinghe Microsoft today announced a new endeavor that aims to make it simpler for Godot developers to get their products into the Xbox PC ecosystem. Dubbed the "XBOX Godot Sample," this is a new public reference for developers using the open-source engine. This is set to serve as an example of how Microsoft GDK, Xbox Services, and PlayFab can be integrated into their projects. The sample is available now on GitHub as a working example. This covers key features in gaming projects that developers may need to release their projects on Xbox PC, with everything from matchmaking and game sign-in to gamepad compatibility with Godot being covered. This release is being called the first step in giving Godot developers the tools to bring their games over to Xbox PC, with more changes to come based on feedback and issue reports. However, the company was clear that this is not related to bringing Godot projects to Xbox consoles. The engine's open development model stops it from accessing console SDKs due to the requirement of NDAs and legal contracts. Here's how it explained this Godot sample project's focus: This is a source-only sample, not a product. It's MIT-licensed at the wrapper layer; the GDK and PlayFab dependencies still require their own installs and license acceptance, consistent with our other XBOX samples. There is no set update cadence for support or maintenance. We’ll watch the repo, monitor issues, and iterate where it makes sense, but this isn't a commercial release. That said, we’re excited to hear your feedback and see any community PRs, as we evolve this together. This is the first step in bringing Godot for XBOX on PC. We plan to evolve it over time based on what the community tells us is most valuable. This sample is built specifically for XBOX on PC. It doesn’t include support for XBOX Series X|S or XBOX One. If you’re already building for XBOX Series X|S or XBOX One, please talk with your XBOX representative. If not, you can get started by signing up here. Game developers can find the XBOX Godot Sample by heading to GitHub over here. Documentation on how to get started with Godot for building an Xbox PC project can be seen here.
    • I don't understand the vision. Do people really want to buy a new computer from Dell with 6 browsers installed? We all keep asking for Microsoft to stop having so much junk on their OS, and adding a bunch of browsers seems to go against that. Ideally, we would just be asked what browser we want during OOBE but Google is just going to pay Dell a bunch of money to include Chrome. Additionally, would you want your phones to start including all the browsers too when you get them? The only thing I ever wanted was to be able to uninstall IE or edge and I believe you are now able to. I do agree that microsoft needs to chill with their "are you sure you don't want to try edge before you install chrome" ads when going to download chrome.
    • It is notable that around 70% of web browser users choose Google Chrome. However, it is puzzling why anyone on Windows would opt for Chrome when Microsoft Edge is often superior in many aspects and comes pre-installed. Edge collects less data, uses less RAM, and is more optimized for Windows as a native Microsoft product. While some may point to bloat in Edge, much of it can be removed with simple tools, requiring no more effort than installing Chrome. Meanwhile, Chrome reportedly downloads large amounts of AI data (4 GB) without explicit consent. I'm sure you Chrome users love that, or? Here is one example of a tool that doesn't even need to be installed to be able to use: https://github.com/TheBobPony/MSEdgeTweaker Although Microsoft’s aggressive promotion of Edge may be questionable, the browser’s current advantages make it a preferable choice over Chrome today, even if Chrome may have been better in the past.
    • JetBrains rolls out IntelliJ IDEA update with Markdown preview fixes and more by David Uzondu Image via JetBrains IntelliJ 2026.1.3 from JetBrains has landed, bringing several highly requested bug fixes that target common UI glitches and terminal rendering issues. If you run tmux inside the integrated terminal, the IDE no longer renders the cursor above the active line. The Markdown preview bug, which was fixed in this release, had annoyed developers for quite some time, as the preview pane failed to render images saved outside the project directory. Instead of displaying the actual image, the IDE simply showed a broken image icon, a problem that stuck around for two years before this update. Over on Windows, developers running WSL can now use wsl.exe to spin up their environments without losing terminal functionality. In previous builds, launching a terminal shell with something like wsl.exe -d ubuntu inside a Windows-based project broke both shell integration and active process detection. Other bug fixes in this release include: An issue where Gradle sync incorrectly reported success as a failure on WSL when using Gradle 9.5.0. A syntax highlighting bug that flagged valid Java for-loop initialization blocks with multiple statements as incorrect. A warning bug that triggered a false non-null local variable alert when using JSpecify annotations. A database generation bug that hid the option to use a DELETE statement instead of a TRUNCATE checkbox. A Kotlin highlighting failure where an assertion error in the Gradle redundant library inspection broke error highlighting. A UI bug where the ComboBox popup lacked a maximum height restriction. A Snowflake syntax error where DataGrip failed to support the "create temp" command. A Svelte syntax parsing failure that incorrectly flagged quotes inside inline expressions. A VCS repository manager deadlock that triggered thread pool exhaustion. A memory leak where the LazyTree component kept all previous versions of a tree in memory. IntelliJ 2026.1.3 is the third bug fix release for the IntelliJ 2026.1 series. The first one landed back in April with a fix for the WSL Python interpreter freeze, another fix for guest participants using Emmet abbreviations, and corrected WildFly server deployment errors.
