CentOS Update for microcode_ctl CESA-2018:0093 centos7

Published: 2018-01-18 06:35:59
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:L/AC:M/Au:N/C:C/I:N/A:N

Detection Type:
Linux Distribution Package

Summary:
Check the version of microcode_ctl

Detection Method:
Checks if a vulnerable version is present on the target host.

Technical Details:
The microcode_ctl Linux Distribution Packages provide microcode updates for Intel and AMD processors. This update supersedes microcode provided by Red Hat with the CVE-2017-5715 (Spectre) CPU branch injection vulnerability mitigation. (Historically, Red Hat 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, Red Hat is providing an microcode update that reverts to the last known good microcode version dated before 03 January 2018. Red Hat 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.

Affected Versions:
microcode_ctl on CentOS 7

Recommendations:
Please Install the Updated Packages.

Solution Type:
Vendor Patch

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
