Debian DLA-2051-1 : intel-microcode security update

medium Nessus Plugin ID 132513
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Debian host is missing a security update.

Description

This update ships updated CPU microcode for some types of Intel CPUs.
In particular it provides mitigations for the TAA (TSX Asynchronous Abort) vulnerability. For affected CPUs, to fully mitigate the vulnerability it is also necessary to update the Linux kernel packages as released in DLA 1989-1.

For Debian 8 'Jessie', these problems have been fixed in version 3.20191115.2~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.
