A defect was discovered in the Python “ssl” module where there is a memoryrace condition with the ssl.SSLContext methods “cert_store_stats()” and“get_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, and 3.12.3.
