Description

The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has microcode_ctl packages installed that are affected by multiple vulnerabilities:

- Observable discrepancy in the RAPL interface for some Intel(R) Processors may allow a privileged user to potentially enable information disclosure via local access. (CVE-2020-8695)

- Improper removal of sensitive information before storage or transfer in some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access. (CVE-2020-8696)

- Improper isolation of shared resources in some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access. (CVE-2020-8698)
