Summary: Updated microcode package fixes security vulnerabilities

Details: This update adds new microcode updates to mitigate CVE-2020-8696 for Intel Skylake server (50654) and Cascade Lake Server (50656 & 50657) processors. The new microcode update mitigates an issue when using an active JTAG agent like In Target Probe (ITP), Direct Connect Interface (DCI) or a Baseboard Management Controller (BMC) to take the CPU JTAG/TAP out of reset and then returning it to reset. 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). 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).
