GNU Emacs: new critical remote shell injection vulnerability.
Red Hat discovered a command injection flaw in the text editor Emacs. It allows a remote, unauthenticated attacker to execute any command on your computer. The vulnerability is activated when you visit a malicious website or link.

@Suiseiseki cve.org is popular and safe to use. JavaScript is a web standard that helps ensure compliance with EU safety regulations and accessibility requirements. It is implemented by 97.69% of web browsers and utilized by 98.3% of all public websites. Therefore, its presence on the CVE site is standard practice for modern web functionality.

@LorenzoAncora >cve.org is popular and safe to use.
You write that, but then I see the following Obfscript;
https://cmp.osano.com/AzyhULTdPkqmy4aDN/46057d56-0263-4cca-abac-9adddada4f3b/osano.js
https://www.cve.org/assets/index-mLL8icbW.js
Those are sufficiently large programs that would be quite trivial to slip proprietary malware in and have such go unnoticed.
Any attacker wouldn't even need to compromise the computer cve.org is running on to attack visitors - they could compromise cmp.osano.com instead.
It seems more JavaScript programs are loaded too, although which ones are not revealed until you run proprietary JavaScript (free and nonfree JavaScript are mixed into the same file), which I refuse to do.
>JavaScript is a web standard that helps ensure compliance with EU safety regulations and accessibility requirements.
JavaScript absolutely destroys accessibility and seems to be primarily used to spy on the user, which doesn't exactly "comply with EU safety regulations".
>It is implemented by 97.69% of web browsers and utilized by 98.3% of all public websites.
97.69% of web browsers have a SEVERE vulnerability and a little less than 98.3% of public websites attack people with proprietary software and spyware huh?
>its presence on the CVE site is standard practice for modern web functionality.
Just because attacking the user is standard practice doesn't mean a website that doesn't function without JavaScript is acceptable.
The only JavaScript your website needs and should have is as follows;
<script>
/* AGPLv3-or-later */
document.body.innerHTML = 'We have detected that you have JavaScript enabled in your browser, please disable it to continue. Please be aware that your browser is severely compromised as it is automatically running malicious JavaScript.'

so you run trojans from two malicious web sites to "prove" that another web site is not malicious. that's as reasonable as asking both coca-cola and pepsi whether their softdrinks are healthy to drink. they don't seem to be affecting only browsers, but also users' brains
that it makes the site completely inaccessible to, per your own numbers, 2.31% of browsers, where web standards recommend graceful degradation instead of big bold red letters stating "don't feel welcome" to those with specific accessibility needs that both major brands of browsers can't tend to, is a big "screw you" to me and others
that it renders computers unusable to access this very site, computers whose manufacturers have abandoned, by refusing to patch known security vulnerabilities that can be exercised with remotely-supplied javascript and refusing to allow owners to patch them by themselves, computers that would still be perfectly usable to visit web sites that actually took the trouble to abide by web standards instead of jumping on the "you must enable javascript" "screw you" mindless bandwagon, adds insult to injury, and more litter to the pile
that a web site that ought to be as security conscious as it goes, and reports vulnerabilities even on browsers, that enable web sites to induce remote execution of arbitrary code on visitors' computers, demands visitors to open up their computers to such risks is not only contradictory to its mission, it's a "screw you" to security education as well.

You do not need JavaScript to write an interactive website - rather the best interactive websites don't use JavaScript and instead use HTML5+CSS+fastCGI; https://git.savannah.gnu.org/cgit/@Suiseiseki HTML5 alone cannot replace JavaScript because it lacks the capability to handle events, manipulate the DOM in real-time, or perform asynchronous operations, which are essential for creating dynamic, accessible and interactive pages.
FastCGI, executing server-side, is computationally more expensive because it requires multiple web requests and can be more vulnerable to remote code execution and misconfigurations than client-side JavaScript.

You do not need any of those things.
If you wanted things to be asynchronous on the same page for a laugh, there's something called iframe.
>FastCGI, executing server-side, is computationally more expensive because it requires multiple web requests
JavaScript requires multiple web requests just to load the JavaScript and then continuous web requests to do each operation, so really JavaScript loses again.
FastCGI really only needs a single request back and forth for every operation.
You can hand optimize the software on the FastCGI end with assembly if you want to minimize how computationally expensive each operation is.
Generally sequentially processing operations on one computer in an efficient manner (doing mostly the same operation over and over again is pretty cache efficient) uses less power than doing the operations in an inefficient way across 1000, 10,000 or millions of computers.
JavaScript is a way to just dump the processing onto the client (and as the client is the one who has to pay for the power, usually the JavaScript is left completely unoptimized).
>can be more vulnerable to remote code execution and misconfigurations than client-side JavaScript.
I'm not sure about the validity of this claim, as fastCGI usually takes user input as POST fields, which is usually properly escaped, unlike a lot of client side JavaScript, which seems to send JavaScript objects, or JSON blobs to the server. -

Client-side processing grants improved responsiveness, better privacy and faster loadings, also reducing the carbon footprint by avoiding unnecessary web requests.

So iframes without JavaScript is bad, but a page full of malicious proprietary JavaScript without iframes is good? Huh.
Have you considered that JavaScript is always the "malicious remote content"?
>allowing criminals to inject malware, steal information, or conduct fraud
Exploitation, information exfiltration etc require JavaScript to pull off - meanwhile you cannot do any of that with just HTML.
>whereas client-side JavaScript is sandboxed within the isolated context of the webpage
Have you considered that there's always a sandbox bypass?
>with same-origin policy restrictions.
Last time I checked those can be applied to iframes just as well.
>Client-side processing grants improved responsiveness, better privacy and faster loadings, also reducing the carbon footprint by avoiding unnecessary web requests.
In reality, I find that cgit is far more responsive and loads faster and has better privacy than JavaScript-based git hosts, which are much slower and really hit the CPU hard - increasing electrical consumption substantially.
If you want to reduce CO₂ emissions, one effective move would be to eliminate JavaScript.
