Amazon Linux 2 : ca-certificates (ALAS-2023-1957)

high Nessus Plugin ID 171824

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of ca-certificates installed on the remote host is prior to 2021.2.50-72. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2023-1957 advisory.

- Certifi is a curated collection of Root Certificates for validating the trustworthiness of SSL certificates while verifying the identity of TLS hosts. Certifi 2022.12.07 removes root certificates from TrustCor from the root store. These are in the process of being removed from Mozilla's trust store.
TrustCor's root certificates are being removed pursuant to an investigation prompted by media reporting that TrustCor's ownership also operated a business that produced spyware. Conclusions of Mozilla's investigation can be found in the linked google group discussion. (CVE-2022-23491)

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

Solution

Run 'yum update ca-certificates' to update your system.
