It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2024-699 advisory.
A defect was discovered in the Python ssl module where there is a memoryrace condition with the ssl.SSLContext methods cert_store_stats() andget_ca_certs(). The race condition can be triggered if the methods arecalled at the same time as certificates are loaded into the SSLContext,such as during the TLS handshake with a certificate directory configured.This issue is fixed in CPython 3.10.14, 3.11.9, 3.12.3, and 3.13.0a5. (CVE-2024-0397)
Tenable has extracted the preceding description block directly from the tested product security advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
