    Package        : linux
    CVE ID         : CVE-2018-3620 CVE-2018-3646
    
    Multiple researchers have discovered a vulnerability in the way the
    Intel processor designs have implemented speculative execution of
    instructions in combination with handling of page-faults. This flaw
    could allow an attacker controlling an unprivileged process to read
    memory from arbitrary (non-user controlled) addresses, including from
    the kernel and all other processes running on the system or cross
    guest/host boundaries to read host memory.
    
    To fully resolve these vulnerabilities it is also necessary to install
    updated CPU microcode (only available in Debian non-free). Common server
    class CPUs are covered in the update released as DSA 4273-1.
    
    For the stable distribution (stretch), these problems have been fixed in
    version 4.9.110-3+deb9u3.
    
    We recommend that you upgrade your linux packages.
