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 DLA 1446-1.
