CVE-2024-0397 (GCVE-0-2024-0397)

Vulnerability from cvelistv5 – Published: 2024-06-17 15:09 – Updated: 2025-11-03 21:50
VLAI?
Summary
A defect was discovered in the Python “ssl” module where there is a memory race condition with the ssl.SSLContext methods “cert_store_stats()” and “get_ca_certs()”. The race condition can be triggered if the methods are called 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.
Severity ?
