MiracleLinux 7 : microcode_ctl-2.1-22.5.el7 (AXSA:2018-2519:02)

medium Nessus Plugin ID 288887

Synopsis

The remote MiracleLinux host is missing a security update.

Description

The remote MiracleLinux 7 host has a package installed that is affected by a vulnerability as referenced in the AXSA:2018-2519:02 advisory.

This update supersedes microcode provided by Asianux with the CVE-2017-5715 (Spectre) CPU branch injection vulnerability mitigation. (Historically, Asianux has provided updated microcode, developed by our microprocessor partners, as a customer convenience.) Further testing has uncovered problems with the microcode provided along with the Spectre mitigation that could lead to system instabilities. As a result, Asianux is providing an microcode update that reverts to the last known good microcode version dated before 03 January 2018.
Asianux strongly recommends that customers contact their hardware provider for the latest microcode updates.
IMPORTANT: Customers using Intel Skylake-, Broadwell-, and Haswell-based platforms must obtain and install updated microcode from their hardware vendor immediately. The Spectre mitigation requires both an updated kernel from Red Hat and updated microcode from your hardware vendor.
CVE-2017-5715 Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected microcode_ctl package.
