Ubuntu Security Notice USN-3561-1
Posted Feb 8, 2018
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 3561-1 - It was discovered that microprocessors utilizing speculative execution and branch prediction may allow unauthorized memory reads via sidechannel attacks. This flaw is known as Spectre. An attacker in the guest could use this to expose sensitive guest information, including kernel memory. This update allows libvirt to expose new CPU features added by microcode updates to guests. On amd64 and i386, new CPU models that match the updated microcode features were added with an -IBRS suffix. Certain environments will require guests to be switched manually to the new CPU models after microcode updates have been applied to the host. Various other issues were also addressed.
