    Ubuntu Security Notice USN-3129-2
    November 11, 2016
    
    linux-raspi2 vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 16.10
    
    Summary:
    
    The system could be made to crash under certain conditions.
    
    Software Description:
    - linux-raspi2: Linux kernel for Raspberry Pi 2
    
    Details:
    
    Ondrej Kozina discovered that the keyring interface in the Linux kernel
    contained a buffer overflow when displaying timeout events via the
    /proc/keys interface. A local attacker could use this to cause a denial of
    service (system crash). (CVE-2016-7042)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 16.10:
      linux-image-4.8.0-1018-raspi2   4.8.0-1018.21
      linux-image-raspi2              4.8.0.1018.21
    
    After a standard system update you need to reboot your computer to make
    all the necessary changes.
    
    ATTENTION: Due to an unavoidable ABI change the kernel updates have
    been given a new version number, which requires you to recompile and
    reinstall all third party kernel modules you might have installed.
    Unless you manually uninstalled the standard kernel metapackages
    (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
    linux-powerpc), a standard system upgrade will automatically perform
    this as well.
