Ubuntu 16.04 ESM / 18.04 LTS : Linux kernel vulnerabilities (USN-5319-1)

medium Nessus Plugin ID 158728

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 16.04 ESM / 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5319-1 advisory.

Enrico Barberis, Pietro Frigo, Marius Muench, Herbert Bos, and Cristiano Giuffrida discovered that hardware mitigations added by Intel to their processors to address Spectre-BTI were insufficient. A local attacker could potentially use this to expose sensitive information.

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

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected kernel package.
