    Ubuntu Security Notice USN-3531-3
    March 29, 2018
    
    intel-microcode update
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 17.10
    - 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:
    
    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. (CVE-2017-5715)
    
    This update provides the corrected 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                 3.20180312.0~ubuntu17.10.1
    
    Ubuntu 16.04 LTS:
      intel-microcode                 3.20180312.0~ubuntu16.04.1
    
    Ubuntu 14.04 LTS:
      intel-microcode                 3.20180312.0~ubuntu14.04.1
    
    After a standard system update you need to reboot your computer to make
    all the necessary changes.
