Summary
To fully resolve these vulnerabilities it is also necessary to install
updated CPU microcode. An updated intel-microcode package (only
available in Debian non-free) will be provided via a separate DLA. The
updated CPU microcode may also be available as part of a system firmware
("BIOS") update.
In addition, this update includes a fix for a regression causing
deadlocks inside the loopback driver, which was introduced by the update
to 4.9.168 in the last security update.
For Debian 8 "Jessie", these problems have been fixed in version
4.9.168-1+deb9u2~deb8u1.
We recommend that you upgrade your linux-4.9 packages.
