The remote NewStart CGSL host, running version MAIN 4.06, has microcode_ctl packages installed that are affected by multiple vulnerabilities:
Insufficient access control in protected memory subsystem for Intel® SGX for 6th, 7th, 8th, 9th Generation Intel® Core™ Processor Families; Intel® Xeon® Processor E3-1500 v5, v6 Families;
Intel® Xeon® E-2100 & E-2200 Processor Families with Intel® Processor Graphics may allow a privileged user to potentially enable information disclosure via local access. (CVE-2019-0117)
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)
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)
Improper isolation of shared resources in some Intel® Processors may allow an authenticated user to potentially enable information disclosure via local access. (CVE-2020-8698)
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)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
