The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4385-1 advisory.

    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)

This update for ucode-intel fixes the following issues :

Updated Intel CPU Microcode to 20200602 (prerelease) (bsc#1172466)

This update contains security mitigations for :

CVE-2020-0543: Fixed a side channel attack against special registers which could have resulted in leaking of read values to cores other than the one which called it. This attack is known as Special Register Buffer Data Sampling (SRBDS) or 'CrossTalk' (bsc#1154824).

CVE-2020-0548,CVE-2020-0549: Additional ucode updates were supplied to mitigate the Vector Register and L1D Eviction Sampling aka 'CacheOutAttack' attacks. (bsc#1156353)
