Hi,

The following vulnerability was published for wolfssl.

CVE-2023-3724[0]:
| If a TLS 1.3 client gets neither a PSK (pre shared key) extension
| nor a KSE (key share extension) when connecting to a malicious
| server, a default predictable buffer gets used for the IKM (Input
| Keying Material) value when generating the session master secret.
| Using a potentially known IKM value when generating the session
| master secret key compromises the key generated, allowing an
| eavesdropper to reconstruct it and potentially allowing access to or
| meddling with message contents in the session. This issue does not
| affect client validation of connected servers, nor expose private
| key information, but could result in an insecure TLS 1.3 session
| when not controlling both sides of the connection. wolfSSL
| recommends that TLS 1.3 client side users update the version of
| wolfSSL used.
