TrueOS 18.03 comes three months after version 17.12 and includes mitigations for the Meltdown and Spectre security vulnerabilities that put billions of devices at risk of attacks. It ports all the fixes from FreeBSD to fix Meltdown for systems using Intel-based processors when running virtual machines. In addition, this release ports all available mitigations from FreeBSD HEAD, including the retpoline mitigation strategy, for the second variant of the Spectre security vulnerability. On top of this, TrueOS developers recommend all users to install the latest microcode update from Intel to fully mitigate Spectre.
