The remote Ubuntu 16.04 ESM / 18.04 LTS / 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4985-1 advisory.

    It was discovered that some Intel processors may not properly invalidate cache entries used by Intel     Virtualization Technology for Directed I/O (VT-d). This may allow a local user to perform a privilege     escalation attack. (CVE-2020-24489)

    Joseph Nuzman discovered that some Intel processors may not properly apply EIBRS mitigations (originally     developed for CVE-2017-5715) and hence may allow unauthorized memory reads via sidechannel attacks. A     local attacker could use this to expose sensitive information, including kernel memory. (CVE-2020-24511)

    Travis Downs discovered that some Intel processors did not properly flush cache-lines for trivial-data     values. This may allow an unauthorized user to infer the presence of these trivial-data-cache-lines via     timing sidechannel attacks. A local attacker could use this to expose sensitive information.
    (CVE-2020-24512)

    It was discovered that certain Intel Atom processors could expose memory contents stored in     microarchitectural buffers. A local attacker could use this to expose sensitive information.
    (CVE-2020-24513)
