----------------------------------------------

             Summary: Websocket text payload data doesn't necessary include trailing zero
                 Key: ASTERISK-28975
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-28975
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Resources/res_http_websocket
    Affects Versions: 17.5.1, 16.11.1, 13.34.0
            Reporter: Nickolay V. Shmyrev


According to websocket spec https://tools.ietf.org/html/rfc6455#section-5.7 and practice there is no trailing zero for text messages, however, the code of ast_websocket_read_string expects them in this part:

{code}
	if (!(*buf = ast_malloc(payload_len + 1))) {
		return -1;
	}

	ast_copy_string(*buf, payload, payload_len + 1);
	return payload_len + 1;
{code}
