Ormandy edited his publish to take away the reference, however not earlier than the Register report was printed.
AMD has confirmed that the bug exists, however that it wants each native administrative entry to the PC in query and particular microcode designed to assault the vulnerability.
“AMD is aware of a newly reported processor vulnerability,” an organization spokesperson confirmed in an electronic mail. “Execution of the attack requires both local administrator level access to the system, and development and execution of malicious microcode.
