As Microsoft preps the [1]next version of Windows , a hole has been spotted in an earlier Great Hope for the company: MS Paint 3D.
The raster graphics and 3D modelling app was part of [2]Microsoft's Creators Update back in 2016 and was released in 2017. The idea was that users would embrace its support for 3D objects and ditch the ancient Microsoft Paint (first introduced with Windows 1.0) for the new shiny.
Things did not turn out quite that way, and [3]Microsoft Paint continues to endure while Paint 3D looks set to follow many of the company's ambitions, ultimately shuffling quietly off into the graveyard where Zune, Band and Media Center are buried.

A [5]vulnerability disclosed by the Zero Day Initiative (ZDI) team will not have helped matters.

The vulnerability, designated [11]CVE-2021-31946 , could let miscreants execute arbitrary code on affected versions of Paint 3D when visiting a malicious page or opening a malicious file.
The problem comes when opening STL files (a format native to the stereolithography CAD software created by 3D Systems, according to Mat Powell, senior staff vulnerability researcher at Trend Micro’s ZDI.) The issue is a good old fashioned parsing cockup where an out-of-bounds read occurs that could result in code execution in the context of the current process.
[12]
[13]
The challenge for hackers would be to persuade a user to open the file, and the attack would need to be paired with a privilege escalation to actually take over a victim's system.
The vulnerability was reported to Microsoft in February and ZDI told The Register : "We are not aware of exploits in the wild or publicly available proof-of-concept code."
[14]
The bug itself was found through fuzzing, a technique where large amounts of random data is squirted at a subject in the hope of uncovering a whoopsie.
Microsoft has now fixed the bug. The patch should slither its way onto customer's computers via the Microsoft Store.
How much longer Paint 3D itself will endure is an open question. Recent Windows Insider builds [15]have quietly removed some 3D bits and pieces from the installation and The Register understands that while Paint endures, Paint 3D is not present in the leaked Windows 11 build.
[16]
We're pretty sure the unloved app won't be featuring on one of Microsoft's hilarious [17]festive knitwear any time soon either. ®

Paint.NET

I would thoroughly recommend [1]Paint.NET as a great piece of software to use instead of Paint.

I will look at it, but looks way overboard for my use case.

It came with a completely unnecessary yet undeletable top-level folder called "3D Objects". This alone was enough for me - in a reasoned, mature and not-at-all petulant decision - to resolve to never ever open the thing. :-)
I've mostly succeeded.

Likewise, and almost totally succeeded (opened it once to look, never again).
Paint on the other hand is my go-to app for all sorts of minor graphics tweaking and adjusting - use it almost daily.

The challenge for hackers would be to persuade a user to open the file application...
FTFY
I actually use Paint 3D
As it does just one thing I want which is to rotate and paste my logo onto a thumbnail / cover image for videos. Otherwise I use paint.
I am sure there are free alternatives that would do that as well or better, but I don't need everything they do, and I would have to learn how to use them, whereas the free already included 3D paint does the job and is good enough for what is strictly a hobby.
