Description

This security bulletin contains information about 4 vulnerabilities.


1) Improper Initialization (CVE-ID: CVE-2020-0522)

CWE-ID: CWE-665 - Improper Initialization

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to improper initialization in the firmware for the Intel(R) Ethernet I210 Controller series of network adapters. A local user can run a specially crafted application to crash the system.


2) Improper access control (CVE-ID: CVE-2020-0523)

CWE-ID: CWE-284 - Improper Access Control

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to improper access restrictions in the firmware for the Intel(R) Ethernet I210 Controller series of network adapters. A local privileged user can bypass implemented security restrictions and perform a denial of service (DoS) attack.


3) Incorrect default permissions (CVE-ID: CVE-2020-0524)
