Microsoft: 32-Bit Windows Kernel Has Hole

Windows 32 bug

Basically, there’s a hole in the 32-bit kernel. What does that mean exactly? In theory, someone could install programs, manipulate data or mess with user account with full rights. It sounds scary, but it’s actually kind of lo- key. Even though Windows 7, Vista, XP and 2K (including their server counterparts) are affected, it’s hard to exploit without you already having super-lax security.

To perform the exploit, you’d need to already have access to the computer — and local access at that. So either someone internally would be performing exploit, or you, the user, forgot to lock your screen. Once the hacker is in, however, s/he could take it’s own account (or yours) and upgrade it to Admin access, letting the hacker do whatever s/he wants.

According to CNET:

To be on the safe side, Microsoft will (of course) be releasing a patch. For the time being, there’s a Microsoft sanctioned workaround disabling the Windows Virtual DOS Machine (NTVDM) subsystem. It closes the hole, and for most users it’s not that big of a deal, since it’s essentially software that lets Windows run DOS and 16-bit Windows software.

And for all you out there using 64-bit versions of Windows, you’re in the clear.

Happy computing.
