Crash seen in tls13_enc API

[Samiya Khanum]

Hi All,

We are seeing a crash in the code below with OpenSSL 1.1.1l  version.
../../../../vendor/openssl/ssl/record/ssl3_record_tls13.c:87: OpenSSL
internal error: Assertion failed: s->s3->tmp.new_cipher != NULL

TLS connection is successful, but when "SSL_shutdown"  is initiated a crash
is seen.
Do we need to set a cipher list in this code?

something like this?
"SSL_CTX_set_cipher_list(ssl_ctx, (char *) "DEFAULT")"

Am I missing something?

*Below is the code for TLS connection:*

 *ctx=SSL_CTX_new(TLS_method());*
* if (ctx == NULL)*
* {*
*    SocketClose(sd);*
*    return FAILURE;*
*  }*

*  con=SSL_new(ctx);*
*  if(con == NULL)*
*  {*
*    SSL_CTX_free(ctx);*
*    SocketClose(sd);*
*    return FAILURE;*
*  }*

*  SSL_set_fd (con, sd);*

*  if(tls1_new(con) != 1)*
*  {*
*    SSL_shutdown(con);*
*    SSL_free(con);*
*    SocketClose(sd);*
*    return FAILURE;*
*  }*

*  err = SSL_connect(con);*
*  if(err == -1)*
*  {*
*    tls1_clear(con);*
*    SSL_shutdown(con);*
*    SSL_free(con);*
*    SocketClose(sd);*
*    return FAILURE;*
*  }*

*   printf("TLS CONNECTION IS SUCCESSFUL");*
*   /* Data send and receive */*

*   /* Close the connection */*
*   if (con != NULL)*
*   {*
*     tls1_clear(con);*
*    /* CRASH is seen when SSL_shutdown is called */*
*     SSL_shutdown(con);*
*     SSL_free(con);*
*   }*


Thanks & Regards,
