Debian DLA-1506-1 : intel-microcode security update (Foreshadow) (Spectre)

medium Nessus Plugin ID 117502

Language:

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 more information please also read the official Intel security advisories at :

-s a-00115.html https://www.intel.com/content/www/us/en/security-center/advisory/intel
-s a-00161.html

For Debian 8 'Jessie', these problems have been fixed in version 3.20180807a.1~deb8u1.

We recommend that you upgrade your intel-microcode packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected intel-microcode package.
