Synopsis

The remote Amazon Linux 2022 host is missing a security update.

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2022-2022-070 advisory.

- Sensitive information accessible by physical probing of JTAG interface for some Intel(R) Processors with SGX may allow an unprivileged user to potentially enable information disclosure via physical access.
(CVE-2022-0005)

- Improper access control for some Intel(R) Xeon(R) Processors may allow an authenticated user to potentially enable information disclosure via local access. (CVE-2022-21131)

- Improper input validation for some Intel(R) Xeon(R) Processors may allow a privileged user to potentially enable denial of service via local access. (CVE-2022-21136)

- Processor optimization removal or modification of security-critical code for some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.
(CVE-2022-21151)

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

Solution

Run 'dnf update --releasever=2022.0.20220518 microcode_ctl' to update your system.
