Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2024-693 advisory.

tpm2-tools: arbitrary quote data may go undetected by tpm2_checkquote (CVE-2024-29038)

tpm2-tools: pcr selection value is not compared with the attest (CVE-2024-29039)

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

Run 'dnf update tpm2-tools --releasever 2023.5.20240805' to update your system.
