Changes for 8.0.1
CVE-2022-41853 - Use of Externally-Controlled Input to Select Classes or Code
('Unsafe Reflection')
-----------------------------------------------------------------------------
Several Progress DataDirect ODBC drivers utilized a version of HyperSQL
Database that was vulnerable to remote code execution described in
CVE-2022-41853. All impacted drivers have been patched to fix this
vulnerability. For details on impacted drivers and fixed versions, refer to
the following KB article:
https://community.progress.com/s/article/DataDirect-ODBC-Critical-Security-
Bulletin-November-2022-CVE-2022-41853

https://docs.progress.com/
Enhancements
------------
* The driver has been enhanced to support key-pair authentication. When
key-pair authentication is enabled (AuthenticationMethod=21), you
can authenticate to Snowflake using a pair of private and public keys. To
configure the driver to use key-pair authentication, you can use the new
Private Key Content (PrivateKeyContent), Private Key File (PrivateKeyFile),
and Private Key Passphrase (PrivateKeyPassphrase) connection options.
* The driver has been enhanced to support the authorization code grant, the
client credentials grant, and the refresh token grant, in addition to the
access token flow. Also, on Windows, the Snowflake Configuration Manager may
now be used to obtain access tokens.
* On Windows, the driver now includes the Snowflake Configuration Manager
for quick configuration and testing of your driver in a web browser. This
tool allows you to:
- Configure data sources and connection strings
- Test connectivity for your data sources and connection strings
- Obtain access tokens for OAuth 2.0 authentication
- Execute SQL commands for testing purposes
* The driver has been modified to map Snowflake data types for fixed-point
numbers to the Numeric data type by default. In addition, the
IntegerFieldMapping connection option has been added to the driver. This
connection option allows you to specify whether fixed-point numbers are
mapped to Numeric or BigInt.
* The product package now includes .pdb files. These files contain debugging
symbols that can be used for diagnosing and debugging issues in the driver.
* The driver is now compiled with a Visual Studio 2022 compiler for Windows
platforms. As a result, you must have Microsoft Visual C/C++ runtime
version 14.40.33810 or higher on your machine to run the driver.
* The driver now allows you to specify whether the driver fetches metadata
for only tables in the database to which you are connected when a database
name is not specified in metadata calls. When enabled, this behavior can
provide better performance for metadata calls by reducing the number of
tables queried. You can use the new Use Session Database For Metadata
(UseSessionDatabaseForMetadata) connection option to configure the driver's
behavior. Refer to the user's guide for details.
* The driver has been enhanced to support connecting to Snowflake partner
applications. You can use the new Partner Application Name
(PartnerApplicationName) connection option to specify the name of the
partner application to which you want to connect. Refer to the user's
guide for details.
* The ICU library files that are installed with the product have been
upgraded to version 74.1. As a part of this upgrade, the ICU library
file names have changed:
- For the 32-bit driver: From ivicu28.dll to ivicu.dll
- For the 64-bit driver: From ddicu28.dll to ddicu.dll
This upgrade is available starting in build 08.02.1072 of the ICU
library files.
* The driver has been enhanced to fall back to JSON query format when the arrow
format is not properly initialized. The driver uses a high-speed arrow
transfer that requires the restricted APIs from java.nio package. When the
JVM is not correctly configured for Java SE 16 and higher, an exception is
returned when the driver executes a query. To allow you to continue executing
queries in this scenario, you can configure the new Arrow Fallback To JSON
(ArrowFallbackToJson) option to switch to the JSON query format.
Note: This option is not currently exposed on the GUI. To configure the
option via the GUI, specify the attribute and setting in the Extend Options
field on the Advanced tab.
Feature details:
* Available: Driver version 08.00.0100 (B1193, U0945, J001002)
* The drivers using base version B0649 and later have been enhanced to
include timestamp in the internal packet logs by default. If you want to
disable the timestamp logging in packet logs, set PacketLoggingOptions=1.
The internal packet logging is not enabled by default. To enable it,
set EnablePacketLogging=1.
* The driver is enhanced to support the COPY command for loading and unloading
data from local file systems and cloud storage platforms.
Changed Behavior
----------------
* The installer program now requires you to install a JRE that is Java SE 11 or
higher before running the installer. In earlier versions, the JRE used by the
installer program was included in the product. However, to avoid potential
security vulnerabilities, the installer program no longer includes a JRE.
Instead, the installer program uses the JRE in your environment to allow for
the most secure version of a JRE to be used.
Notes:
- This change does not affect the JVM requirements for the driver. For the latest
driver requirements, refer to the Product Compatibility Guide:
https://docs.progress.com/bundle/datadirect-product-compatibility/resource/
datadirect-product-compatibility.pdf
- The installer program cannot remove the already installed JRE files from the
install directory automatically. Remove them manually.
- To install the 32-bit drivers on 64-bit Windows platforms and start the SQL
engine service, the installer requires the 32-bit version of Java SE 11 or
higher installed on your machine and defined on your path.
* The installer program has been updated to no longer install common components
for drivers that do not use them. As a result, the installer program no longer
installs the following common components for the Snowflake driver:
- OpenSSL library files, such as ivopenssl30.dll, ddopenssl30.dll, fips.dll,
and openssl.cnf.
- Curl library files, such as ivcurl28.dll and ddcurl28.dll.
If the files are not used by any other DataDirect driver on your machine, you
can safely remove them from existing product directories.
Release 8.0.0 Features
The Progress DataDirect for ODBC for Snowflake provides enhanced
performance over the native ODBC Snowflake driver. It supports create,
read, update, and delete operations. In addition, the driver:
* Serves as a complete pass-through driver, leveraging the SQL engine
functionality of Snowflake to execute SQL queries.
* Supports integration with third-party applications: Tableau, Crystal Reports,
Microsoft Excel, Microsoft Access, Microsoft SQL Linked Server,
SQL Server Integration Services, and Microsoft Power BI.
* Provides proxy support using ProxyHost, ProxyPassword, ProxyPort, and
ProxyUser connection options.
* Supports the handling of large result sets with configurable paging using the
FetchSize connection option.
* The driver supports authentication methods, such as, OAuth and
browser-based single sign-on (SSO).
Notes, Known Problems, and Restrictions
The following are notes, known problems, and restrictions with the latest release
of the driver:
* The driver does not support specifying values for the same connection
option multiple times in a connection string or DSN. If a value is
specified using the same attribute multiple times or using both
long and short attributes, the connection may fail or the driver may
not behave as intended.
* The driver does not support plain text inserts in columns of binary data.
Data inserted into columns containing binary data, requires a conversion
to hex format.
* The driver does not support scrollable cursor operations on result set data.
* The driver supports Windows 32 and 64-bit, Linux 32 and 64-bit platforms.
* The driver gives a warning message when a SELECT query is run for the first
time in a new connection instance, using a console application and OpenJDK 11.
* The OAuth token is valid for 10 minutes, if no connection instance is
established or after a connection instance is terminated. A token does not
expire in an uninterrupted connection instance.
* For browser-based single sign-on connections, a message appears on the
browser "Your identity was confirmed and propagated to Snowflake JDBC driver.
You can close this window now and go back where you started from."
This is due to the underlying jdbc layer architecture of the driver.
* The active connections viewed on the Snowflake console are termed as JDBC
connections. This is due to the underlying JDBC layer architecture of the
driver.
* The browser-based SSO authentication does not work in SQL engine server
mode when Snowflake server runs as a Windows service.
Driver WorkAround Options
Progress DataDirect has included non-standard connection options (workarounds)
for the driver that enable you to take full advantage of packaged ODBC-enabled
applications requiring non-standard or extended behavior. Refer to the chapter
"WorkAround options" in THE PROGRESS DATADIRECT FOR ODBC DRIVERS REFERENCE for a
description of these options.
