Security updates for Intel NUC firmware (INTEL-SA-00084)

Intel ID: INTEL-SA-00084
Product family: Intel® NUC Kits
Impact of vulnerability: Elevation of Privilege
Severity rating: Critical
Original release: Oct 06, 2017

This update improves protection against mitigates multiple vulnerabilities related to security features in Intel® NUC system firmware (BIOS). BIOS Administrator and User password bypass: Insufficient protection of password storage in system firmware for NUC7i3BNK, NUC7i3BNH, NUC7i5BNK, NUC7i5BNH, NUC7i7BNH versions BN0049 and below allows local attacker to bypass Administrator and User passwords via access to password storage. SPI Write Protection Bypass: Insecure platform configuration in system firmare for NUC7i3BNK, NUC7i3BNH, NUC7i5BNK, NUC7i5BNH, NUC7i7BNH versions BN0049 and below allows an attacker with physical presence to run arbitrary code via unauthorized firmware modification during BIOS Recovery. SMM Privilege Elevation: Insufficient input validation in system firmware for Intel® NUC systems allows local attacker to execute arbitrary code via manipulation of memory. Boot Guard Bypass: Incorrect policy enforcement in system firmware for Intel® NUC systems allows attacker with local or physical access to bypass enforcement of integrity protections via manipulation of firmware storage. Dangerous SPI Opcode Protections: Insufficient policy enforcement in system firmware for Intel® NUC systems allows attacker with local or physical access to violate integrity or availability of nonvolatile storage for firmware via specially crafted accesses to nonvolatile storage. Intel highly recommends that users update to the latest version. Intel would like to thank Nikolaj Schlaj for reporting CVE-2017-5700 and CVE-2017-5701 and working with us on coordinated disclosure. Intel would like to thank Embedi for reporting CVE-2017-5721 and CVE-2017-5722 and working with us on coordinated disclosure.[…]
