USN-3542-1 addressed vulnerabilities in the Linux kernel for Ubuntu
14.04 LTS. This update provides the corresponding updates for the
Linux Hardware Enablement (HWE) kernel from Ubuntu 14.04 LTS for
Ubuntu 12.04 ESM.
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 for the i386 (CVE-2017-5753
only) and amd64 architectures.
