Synopsis
The remote Debian host is missing a security update.Description
Security researchers identified speculative execution side-channel methods which have the potential to improperly gather sensitive data from multiple types of computing devices with different vendors’processors and operating systems.
This update requires an update to the intel-microcode package, which is non-free. It is related to DLA-1446-1 and adds more mitigations for additional types of Intel processors.

For Debian 8 'Jessie', these problems have been fixed in version 3.20180807a.1~deb8u1.
We recommend that you upgrade your intel-microcode packages.
