CVE-2024-39689
Description
A flaw was found in Certifi, a curated collection of Root Certificates for validating the trustworthiness of SSL certificates while verifying the identity of TLS hosts. Certain versions of Certifi recognized root certificates from 'GLOBALTRUST'. However, pursuant to an investigation that identified "long-running and unresolved compliance issues," GLOBALTRUST's root certificates are now removed from the root store.
Statement
Red Hat ships an affected version of python-certifi; however, the product includes a separate CA bundle installed from RHEL with a custom product-based patch. Hence it is not using the certificates provided upstream and not affected by the flaw. Red Hat Product Security team does not foresee any impact on the confidentiality, integrity or availability of system for this product due to this flaw.
Mitigation
This issue can be mitigated by adding the root CAs in question to /etc/pki/ca-trust/source/blacklist on RHEL 8 or /etc/pki/ca-trust/source/blocklist on RHEL 9 and running update-ca-trust.

Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
