Microsoft Finally Fixes Paint, Because Apparently Even Doodling Needed a Bloody RCE

Right, here’s the shitshow: Microsoft has fixed a remote code execution vulnerability in Paint. Yes, Paint. That ancient little scribble toy somehow managed to become a security problem, because of course it fucking did. The fix has reached the Microsoft Store, but not Windows Update, which is peak Microsoft: patch the damn thing, then make sure half the admins have to play scavenger hunt to actually get it.

The bug affects the app version of Paint, and the patched version is being pushed through the Store. So if you’re expecting your usual patch management through Windows Update, tough shit — that’s not where this one’s landing. Admins who like having a sane, centralized update process are once again being told to go herd cats in a different corner of the Microsoft ecosystem.

The article points out the obvious pain in the arse: Store-delivered updates are a nuisance in managed environments. If your organization blocks, restricts, or generally treats the Microsoft Store like the malware-adjacent clown car it often resembles, then getting this fix deployed becomes more annoying than it should be. Because why make security patching straightforward when you can make it weird and fragmented instead?

The vulnerability itself is serious enough to matter, since remote code execution bugs are the kind of thing that can ruin your day, your week, and possibly your employment status if some bastard exploits them. And yet the remediation path is split off into the Store mechanism, which means defenders get the usual Microsoft special: “Yes, we fixed it. No, not in the place you expected. Good luck, fuckers.”

The takeaway is simple: if you rely on Paint being present in your environment — and apparently some poor souls still do — then you need to verify the app version and make sure the Store update has actually been applied. Don’t assume Windows Update has your back here, because it bloody well doesn’t. Check your app management, check your Store policies, and check whether your users are still running the vulnerable version of this prehistoric paintbox.

In other words, Microsoft did eventually put out the fire, but only after hiding the extinguisher in a different building and not telling anyone which cupboard it was in. Standard operating procedure, really.

I remember once “fixing” a user’s machine by removing three toolbars, a weather app, and a mysterious drawing utility they swore they never installed. Turned out they’d been opening every attachment like it was Christmas morning. When the machine finally stopped screaming, I told them the real vulnerability was between the chair and the keyboard. They complained to management, management complained to me, and I printed their email. On the broken printer. Out of spite.
