Various OpenBSD developers have stated that there are OS vulnerabilities introduced by the use of video card hardware features by X. It's been a while since I read the details, but I wonder if the GPU chips might be able to run in user (non-priviledged) mode only, thus precluding the possibility of exploits based upon direct hardware access given the video card software. -- fedora-list mailing list [email protected] To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
