    Version 8.0.2 

    • The installer program has been enhanced to support Azul Zulu JRE 11. As a result of this change, the installer has ended support for platforms that do not support Java SE 8 or higher. The installer supports the following operating systems after the enhancement:
      • Windows 8.1 or higher
      • Windows Server 2012 RC2 or higher
      • UNIX/Linux: Any operating system on a machine using a JRE that is Java SE 8 or higher (LTS version), including Oracle JDK, OpenJDK, and IBM SDK (Java) distributions.
      Important: These changes do not affect the operating system requirements of the driver.*
    • The default version of the OpenSSL library has been upgraded to version 1.1.1t, which fixes the following security vulnerabilities:*
      • X.400 address type confusion in X.509 GeneralName (CVE-2023-0286)
      • Use-after-free following BIO_new_NDEF (CVE-2023-0215)
      • Double free after calling PEM_read_bio_ex (CVE-2022-4450)
      • Timing Oracle in RSA Decryption (CVE-2022-4304)

      Version 1.1.1t also addresses vulnerabilities resolved by earlier versions of the library. For more information on the installed library files, refer to the readme.
      For more information on the OpenSSL vulnerabilities resolved by this upgrade, refer to the corresponding OpenSSL announcements at

    • OpenSSL library 1.1.1n has been replaced with version 1.1.1t. In addition to fixing multiple new vulnerabilities, version 1.1.1t also addresses the vulnerabilities resolved by version 1.1.1n:*
      • Infinite loop in BN_mod_sqrt() reachable when parsing certificates (CVE-2022-0778)
      • BN_mod_exp may produce incorrect results on MIPS (CVE-2021-4160)
    • 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 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.
    • For UNIX/Linux, a Password Encryption Tool, called ddencpwd, is now included with the product package. It encrypts passwords for secure handling in connection strings and odbc.ini files. At connection, the driver decrypts these passwords and passes them to the data source as required. Passwords can be encrypted for any option.
