A flaw that has been present in Microsoft software since 1993, and still affects Windows 7, has been published by a security researcher.

Tavis Ormandy published details of the flaw on the Neohapsis mailing list on Tuesday.

The problem lies in the Virtual DOS Machine, Heise security explained on Wednesday.

Workarounds include users disabling the MS-DOS subsystem by starting the group policy editor and enabling the "Prevent access to 16-bit applications" option in a sub-menu of the computer configuration tab, according to the Heise article.
