Synopsis

The remote machine is affected by multiple vulnerabilities.

Description

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(R) Processors may allow an authenticated user to potentially enable information disclosure via local access. (CVE-2020-0543)

- Cleanup errors in some Intel(R) 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(R) Processors may allow an authenticated user to potentially enable information disclosure via local access. (CVE-2020-0549)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
