"The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by a vulnerability as referenced
in the USN-3521-1 advisory.

    Jann Horn discovered that microprocessors utilizing speculative execution and branch prediction may allow
    unauthorized memory reads via sidechannel attacks. This flaw is known as Spectre. A local attacker could
    use this to expose sensitive information, including kernel memory.

    This update provides mitigations to address the issue, along with compatibility fixes for the
    corresponding Linux kernel updates.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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