The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has microcode_ctl packages installed that are affected by multiple vulnerabilities:
Incomplete cleanup from specific special register read operations in some Intel® Processors may allow an authenticated user to potentially enable information disclosure via local access. (CVE-2020-0543)
Cleanup errors in some Intel® Processors may allow an authenticated user to potentially enable information disclosure via local access. (CVE-2020-0548)
Cleanup errors in some data cache evictions for some Intel® Processors may allow an authenticated user to potentially enable information disclosure via local access. (CVE-2020-0549)
Incomplete cleanup in some Intel® VT-d products may allow an authenticated user to potentially enable escalation of privilege via local access. (CVE-2020-24489)
Improper isolation of shared resources in some Intel® Processors may allow an authenticated user to potentially enable information disclosure via local access. (CVE-2020-24511, CVE-2020-8698)
Observable timing discrepancy in some Intel® Processors may allow an authenticated user to potentially enable information disclosure via local access. (CVE-2020-24512)
Observable discrepancy in the RAPL interface for some Intel® 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® Processors may allow an authenticated user to potentially enable information disclosure via local access. (CVE-2020-8696)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
