Package : intel-microcode
Version : 3.20190514.1~deb8u1

Debian Bug : 929007

This update ships updated CPU microcode for most types of Intel CPUs. It
provides microcode support to implement mitigations for the MSBDS,
MFBDS, MLPDS and MDSUM hardware vulnerabilities.

To fully resolve these vulnerabilities it is also necessary to update
the Linux kernel packages. Please refer to DLA-1787-1 for the Linux
kernel updates required to mitigate these hardware vulnerabilities on
Intel processors.

For Debian 8 "Jessie", these problems have been fixed in version
3.20190514.1~deb8u1 of the intel-microcode package, and also by the
Linux kernel package updates described in DLA-1787-1.

We recommend that you upgrade your intel-microcode packages, and Linux
kernel packages.

Further information about Debian LTS security advisories, how to apply
these updates to your system and frequently asked questions can be found
at: https://wiki.debian.org/LTS
