DLA 1481-1: linux-4.9 security update

Package : linux-4.9
Version : 4.9.110-3+deb9u4~deb8u1
CVE ID : CVE-2018-3620 CVE-2018-3646
Debian Bug : 906769

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.

For Debian 8 "Jessie", these problems have been fixed in version
4.9.110-3+deb9u4~deb8u1.

We recommend that you upgrade your linux-4.9 packages.
