| * When negotiating TLS version on server side, do not fall back to the | |
| TLS 1.2 implementation of the protocol if it is disabled. | |
| - If the TLS 1.2 implementation was disabled at build time, a TLS 1.2 | |
| client could put the TLS 1.3-only server in an infinite loop processing | |
| a TLS 1.2 ClientHello, resulting in a denial of service. Reported by | |
| Matthias Mucha and Thomas Blattmann, SICK AG. | |
| - If the TLS 1.2 implementation was disabled at runtime, a TLS 1.2 client | |
| was able to successfully establish a TLS 1.2 connection with the server. | |

| Fixes CVE-2024-28836. |
