After looking at the slides for Loic Duffet's presentation
http://72.14.203.104/search?q=cache:y-G4z3W2zuQJ:www.cansecwest.com/slides06/csw06-duflot.ppt+%27Lo%C3%AFc+Duflot%27&hl=en&gl=us&ct=clnk&cd=1&ie=UTF-8
on x86 hardware vulnerabilities at CanSecWest,
I'm wondering if *any* OS that allows the video card to
access PC memory can be 'rooted'.
Is this a correct conclusion from Loic's presentation?
Is simply running run X windows sufficient to permit 'rooting'
of OpenBSD, or must the memory aperture of the video card
be non-zero as well?
What changes would have to be made to PC hardware
architecture to plug the security holes Loic has identified?
Thanks,
Dave Feustel
