When the (by + default enabled) maximum fragment length extension is disabled in the + config and the application data buffer passed to mbedtls_ssl_write + is larger than the internal message buffer (16384 bytes by default), the + latter overflows. The exploitability of this issue depends on whether the + application layer can be forced into sending such large packets.
