  • Segmentation fault in SSL_check_chain (CVE-2020-1967)
  • rsaz_512_sqr overflow bug on x86_64 (CVE-2019-1551)  
• The driver has been enhanced to support Sybase Extended Password Encryption and Sybase Extended Plus Encrypted Password, which use the asymmetrical key type. This provides stronger password encryption for the secure transmission of public key passwords over networks. Refer to Authentication Method for details.*
• The driver has been enhanced to support BINARY and VARBINARY data types when using the bulk load protocol. Refer to Data Types for details.*
• 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.*
• OpenSSL library 1.0.2r has been replaced with version 1.0.2u. In addition to fixing multiple new vulnerabilities, version 1.0.2u also addresses the vulnerabilities resolved by version 1.0.2r.*
  Version 1.0.2u of the OpenSSL library fixes the following security vulnerabilities:
  • x64_64 Montgomery squaring procedure used in exponentiation with 512-bit moduli (CVE-2019-1563)
  • Padding Oracle in PKCS7_dataDecode and CMS_decrypt_set1_pkey (CVE-2019-1563)
  • Compute ECC cofactors if not provided during EC_GROUP construction (CVE-2019-1547)
  • Installation paths in diverse Windows builds (CVE-2019-1552)

  Note: By default, the driver will attempt to load version 1.1.1 of the library; however, if the library cannot be loaded, the driver will fall back to version 1.0.2.

• The Driver Manager for UNIX/Linux has been enhanced to support setting the Unicode encoding type for applications on a per connection basis. By passing a value for the SQL_ATTR_APP_UNICODE_TYPE attribute using SQLSetConnectAttr, your application can specify the encoding at connection. This allows your application to pass both UTF-8 and UTF-16 encoded strings with a single environment handle.*
  The valid values for the SQL_ATTR_APP_UNICODE_TYPE attribute are SQL_DD_CP_UTF8 and SQL_DD_CP_UTF16. The default value is SQL_DD_CP_UTF8.
  This enhancement is available in build 07.16.0398 of the driver manager.
• The default OpenSSL library version has been updated to 1.1.1d.*
• The default OpenSSL library version has been updated to 1.0.2r:*

• The new CryptoLibName and SSLLibName connection options allow you to designate the OpenSSL libraries used when SSL is enabled.

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.
  • The installer program cannot remove the already installed JRE files from the install directory automatically. Remove them manually.
• The product package no longer includes the ODBC Cursor library file (odbccurs.so) because it has some known security vulnerabilities that could potentially expose you to security risks.*
  Note: The installer program cannot remove the ODBC Cursor library file automatically while installing a new version of the driver. Remove it manually.
• The product no longer includes version 1.1.1 of the OpenSSL library. The library will reach the end of its product life cycle in September 2023 and will not receive any security updates after that. Note that continuing to use the library after September 2023 can potentially expose you to security vulnerabilities.*

  Note: As a result of this change, when installing a new version of the product, the installer program will automatically remove version 1.1.1 of the library from the install directory, which will impact all the DataDirect ODBC drivers installed on a machine.

• The product no longer includes version 1.0.2 of the OpenSSL library. The library has reached the end of its product life cycle and is not receiving security updates anymore. Note that continuing to use the library could potentially expose you to security vulnerabilities.*
  Note: As a result of this change, when installing a new version of the driver, the installer program will automatically remove version 1.0.2 of the library from the install directory.
• The Allowed OpenSSL Versions (AllowedOpenSSLVersions) connection option has been deprecated as the driver currently supports only version 3.0 of the OpenSSL library.
• The crypto protocol versions prior to TLSv1 are no longer supported.

Version 7.1.5

Enhancements

• The OpenSSL library was upgraded to version 1.0.0r, which fixes the CVE‐2015‐0204 (FREAK) vulnerability. See "RSA silently downgrades to EXPORT_RSA [Client] (CVE‐2015‐0204)" at https://www.openssl.org/news/secadv_20150108.txt for more
  information.
• The new PRNGSeedSource connection option allows you to specifies whether the driver uses a file or the RAND_poll function as the seed source for SSL key generation.
• The new PRNGSeedFile connection option allows you to specify the entropy‐source file or device used as a seed for SSL key generation.
• The new Crypto Protocol Version connection option allows you to specify the cryptographic protocols used when SSL is enabled. This option can be used to avoid vulnerabilities associated with SSLv3 and SSLv2, including the POODLE vulnerability.

Version 7.1.4

Enhancements

• The new KeepAlive connection option allows you to use TCP Keep Alive to maintain idle TCP connections.
