DHS Warns of UEFI Hardware Vulnerabilities

The CERT/CC at Carnegie Mellon University today released three advisories warning of vulnerabilities that affect some unified extensible firmware interface UEFI systems and the BIOS of some Intel chipsets. Hardware and firmware vulnerabilities, such as these reported by Corey Kallenberg of MITRE...

UEFI implementations do not properly secure the EFI S3 Resume Boot Path boot script

Overview Some UEFI systems fail to properly restrict access to the boot script used by the EFI S3 Resume Boot Path, allowing an authenticated, local attacker to bypass various firmware write protections. Description According to Rafal Wojtczuk of Bromium and Corey Kallenberg of The MITRE...

Intel BIOS locking mechanism contains race condition that enables write protection bypass

Overview A race condition exists in Intel chipsets that rely solely on the BIOSCNTL.BIOSWE and BIOSCNTL.BLE bits as a BIOS write locking mechanism. Successful exploitation of this vulnerability may result in a bypass of this locking mechanism. Description CWE-362: Concurrent Execution using Share...
