Intel fixes 95 vulnerabilities

Intel addressed 95 vulnerabilities in the Patch Tuesday November 2020, including some critical vulnerabilities that affect Intel Wireless Bluetooth and Intel Active Management Technology (AMT) products.

The issues are discussed in detail in the 40 security tips published by Intel in Product Security Center, with the company delivering security and operational updates to users through the Intel Platform Update (IPU) process.Intel

Intel provides a list of all affected products and recommendations for vulnerable products at the end of each consultation, as well as contact information for those who wish to report other security issues or vulnerabilities identified in Intel-branded products or technology.

Among the security updates released on Tuesday, Intel encountered a critical vulnerability with a CVSS score of 9,4 / 10 on Intel Active Management Technology (AMT) and Intel Standard Manageability (ISM) products.

The defect (monitored as CVE-2020-8752) is an IPv6 subsystem entry of Intel AMT and ISM (versions prior to 11.8.80, 11.12.80, 11.22.80, 12.0.70, 14.0) that allows remote unauthorized privilege change.

Successful exploitation requires setting up vulnerable products with IPv6 which is not a default setting according to Intel.

A second critical security flaw (CVE-2020-12321) with a CVSS severity score of 9,6 / 10 affecting some Intel Wireless Bluetooth products was also addressed in the Intel update in November.

The new vulnerabilities of the Intel CPU (CVE-2020-8694and CVE-2020-8695) were named PLATYPUS and were discovered by an international team of researchers from the University of Technology Graz, the CISPA Helmholtz Center for Information Security and the University of Birmingham.

Successful exploitation of the two vulnerabilities could lead to information leakage from the Running Average Limit Power (RAPL) interface, which is used to monitor and manage CPU and DRAM power consumption.

The researchers also released a video showing how one could steal AES-NI keys from the Intel SGX with a PLATYPUS attack.
