Microsoft Patching 17-year-old Windows/DOS Bug

Last month we reported that Tavis Ormandy, a security researcher at Google, discovered a security flaw in the Virtual DOS Machine that can allow a nefarious user to inject code into the kernal and possibly install malware.

The flaw spanned iterations of Windows operating system over the last 17 years, including:

  • Windows 2000
  • Windows XP
  • Windows Server 2003
  • Windows Vista
  • Windows Server 2008
  • Windows 7

According to the BBC, Microsoft will be rolling out a fix to this bug in a February Security Update. The update will fix five vulnerabilities that allow attackers to hijack a Windows PC and run their own programs on it.

The patch is expected to hit on Tuesday, February 9 but it's a good idea to have automatic updates turned on so that your OS will do the checking for you.

    It looks that all MS staff does is eat and shit, never checks old console. Bill could hire a team which would work on patches. Come on Microsoft.
