- Summary
- Memory race condition in ssl.SSLContext certificate store methods
- Details
-
A defect was discovered in the Python “ssl” module where there is a memory race condition with the ssl.SSLContext methods “certstorestats()” and “getcacerts()”. 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.
