Description: | An issue was discovered in Python before 3.8.18, 3.9.x before 3.9.18,
3.10.x before 3.10.13, and 3.11.x before 3.11.5. It primarily affects
servers (such as HTTP servers) that use TLS client authentication. If
a TLS server-side socket is created, receives data into the socket
buffer, and then is closed quickly, there is a brief window where the
SSLSocket instance will detect the socket as "not connected" and won't
initiate a handshake, but buffered data will still be readable from
the socket buffer. This data will not be authenticated if the server-
side TLS peer is expecting client certificate authentication, and is
indistinguishable from valid TLS stream data. Data is limited in size
to the amount that will fit in the buffer. (The TLS connection cannot
directly be used for data exfiltration because the vulnerable code
path requires that the connection be closed on initialization of the
SSLSocket.)
