making non-savy surfers suffer some sort of issue, masked under some other extension, blah blah blah.

But I thought we weren't talking anymore. I'm so glad you (guys) decided to break the ice.  

That's precisely what I warned about, with that "fix" non-savvy people will get the wrong feeling of safety, and then infect themselves with WebP.

So perhaps I agree with you, better to do nothing than relax yourself with such "solutions". I'm not sure about the chance/infection rate.

Who are you, I don't remember. I recently fell off the second floor of a hooch we were clearing up in a far away country, so it could reflect on my memory.

The floor simply didn't hold my weight, I'm tall.

Many servers run on Linux, not Windows.

You completely missed the point! If MSE can scan for the exploit on Windows, then surely widely-available AV software can scan for the exploit on Linux.

Serpent 52 is patched. Try a pre-September version.

Actually, you meant September 9 version. as September 16 version is the version to fix the webp security vulnerability.

This is how it looks like:

To stop the chain of events that can lead to the success of an exploit, a few tricks may be sufficient even in unpatched browsers.
I have seen exploits rendered harmless with the renderer at IL AppContainer.
In my opinion those who have an unpatched browser,listed on the anti-exploit list,and take a number of expedients that at various points can counteract the chain of events that can lead to the success of an exploit,i.e., leverage an unpatched vulnerability in the browser and/or OS can be reasonably safe.

Using uBlock Origin with dynamic filtering enabled is considered by all security experts to be a security surplus in the browser.

Ha ha, good to know I had the fix already. I feel safer :P.  I also tried in mypal, so I guess that is also fixed. 

As per trying on a non-fixed version, I completely trust what you say: I tried even though I thought I was unprotected. Put to think about it, not the first time, really ;P

How were you able to determine that Mypal is patched? Just I wanted to know this as well but am unsure how to make the determination. Thank you, man.

Where did the idea that unpatched browser will certainly crash come from? Still have two unpatched browsers installed, Edge 94 and Firefox 110, none of them crash on that image.

Were did you get that link, Mina, I'm trying to read it but my eyes wont let me me get very far - would you be so kind as so post that link you have in your address bar as and I read the entire thread and cant find it. Either its not there, or the green tea is not working very well this morning

I'd like to read that article where "all security experts considered" this, thanks.

Just to show the skeptics that the vulnerability is real and not mere fearmongering, you can download a "bad" WebP image here:

https://github.com/mistymntncop/CVE-2023-4863/raw/main/bad.webp

Important note: This WebP file does not contain any malware or exploit code! I wouldn't link to such a thing here on MSFN, even with a warning (and if it did, I don't think GitHub would allow it anyway). But it does trigger a buffer overflow in unpatched software, likely leading the software to crash. (For example, I got the "Aw, snap!" page in 360EE.) Therefore, you can use this as a "quick-and-dirty" test for vulnerable, unpatched software.

 

It has nothing to do with scepticism, it's just caution!

"mistymntncop" looks like a random account on github, nothing official.

Has no projects:

https://github.com/mistymntncop?tab=projects

Not even a description of who that man (woman?) is.

Thank you! Wow do I feel red in the face ... guess I've not been able to shake all the cobwebs from my brain this morning. Looks like Mypal is indeed patched then so please disregard my posting to you @dmiranda and @mina7601. I've also never felt safer.

Here in benefit of dynamic filtering referring only to third-party frame blocking:

https://github.com/gorhill/uBlock/wiki/Dynamic-filtering:-Benefits-of-blocking-3rd-party-iframe-tags

as you can see it is a formidable defense against exploits as well.
Those using higher dynamic filtering (Medium Mode or Hard Mode obviously have more protection at the security/privacy level.

I use Hard Mode + TLD's
