Summary:	The remote host is missing an update for the 'intel-microcode' package(s) announced via the USN-4385-1 advisory.
Description:	Summary: The remote host is missing an update for the 'intel-microcode' package(s) announced via the USN-4385-1 advisory. Vulnerability Insight: It was discovered that memory contents previously stored in microarchitectural special registers after RDRAND, RDSEED, and SGX EGETKEY read operations on Intel client and Xeon E3 processors may be briefly exposed to processes on the same or different processor cores. A local attacker could use this to expose sensitive information. (CVE-2020-0543) It was discovered that on some Intel processors, partial data values previously read from a vector register on a physical core may be propagated into unused portions of the store buffer. A local attacker could possible use this to expose sensitive information. (CVE-2020-0548) It was discovered that on some Intel processors, data from the most recently evicted modified L1 data cache (L1D) line may be propagated into an unused (invalid) L1D fill buffer. A local attacker could possibly use this to expose sensitive information. (CVE-2020-0549) Affected Software/OS: 'intel-microcode' package(s) on Ubuntu 14.04, Ubuntu 16.04, Ubuntu 18.04, Ubuntu 19.10, Ubuntu 20.04. Solution: Please install the updated package(s). CVSS Score: 2.1 CVSS Vector: AV:L/AC:L/Au:N/C:P/I:N/A:N
