| summary: Panic on large handshake records in crypto/tls |
| description: |- |
| Large handshake records may cause panics in crypto/tls. |
| |
| Both clients and servers may send large TLS handshake records which cause |
| servers and clients, respectively, to panic when attempting to construct |
| responses. |
| |
| This affects all TLS 1.3 clients, TLS 1.2 clients which explicitly enable |
| session resumption (by setting Config.ClientSessionCache to a non-nil value), |
| and TLS 1.3 servers which request client certificates (by setting |
| Config.ClientAuth >= RequestClientCert). |
