========================================================================== Ubuntu Security Notice USN-3531-1 January 11, 2018
intel-microcode update ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 17.10 - Ubuntu 17.04 - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS
Summary:
The system could be made to expose sensitive information.
Software Description: - intel-microcode: Processor microcode for Intel CPUs
Details:
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. A local attacker could use this to expose sensitive information, including kernel memory. (CVE-2017-5715)
This update provides the microcode updates required for the corresponding Linux kernel updates.
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 17.10: intel-microcode 3.20180108.0~ubuntu17.10.1
Ubuntu 17.04: intel-microcode 3.20180108.0~ubuntu17.04.1
Ubuntu 16.04 LTS: intel-microcode 3.20180108.0~ubuntu16.04.2
Ubuntu 14.04 LTS: intel-microcode 3.20180108.0~ubuntu14.04.2
After a standard system update you need to reboot your computer to make all the necessary changes.
