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)

A flaw was found in hw. Improper access control for some Intel(R) Xeon(R) processors may potentially allow an authenticated user to enable information disclosure via local access. (CVE-2022-21131)

A flaw was found in hw. Improper input validation for some Intel(R) Xeon(R) processors may allow a privileged user to enable a denial of service via local access. (CVE-2022-21136)

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

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

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

Solution
