- The default version of the OpenSSL library has been upgraded to version 1.1.1k, which fixes the following security vulnerabilities:*
- CA certificate check bypass with X509_V_FLAG_X509_STRICT (CVE-2021-3450)
- NULL pointer deref in signature_algorithms processing (CVE-2021-3449)
- Null pointer deref in X509_issuer_and_serial_hash() (CVE-2021-23841)
- Integer overflow in CipherUpdate (CVE-2021-23840)
Version 1.1.1k 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 1.1.1i has been replaced with version 1.1.1k. In addition to fixing multiple new vulnerabilities, version 1.1.1k also addresses the vulnerability resolved by version 1.1.1i: Incorrect behavior of the GENERAL_NAME_cmp function (CVE-2020-1971).*
The driver has been enhanced to support the SCRAM-SHA-256-PLUS authentication method, which uses channel binding for establishing a secure connection with PostgreSQL (v11.0 and higher).*
- The driver has been enhanced with the new Batch Mechanism (BatchMechanism)
connection option, which specifies the preferred mechanism for executing
batch insert operations. By setting Batch Mechanism to 2 (MultiRowInsert) or
3 (Copy), the driver can achieve substantial performance gains when
performing batch inserts. The default setting is BatchMechanism=1 (SingleRowInsert). Refer to the installed readme for details.*
- OpenSSL library version 1.1.1g has been replaced with version 1.1.1k. In addition to fixing multiple new vulnerabilities, version 1.1.1k also addresses the vulnerabilities resolved by version 1.1.1g:*
- 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 the following data types: Citext, Float, and Tinyint.
- 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
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 new AllowedOpenSSLVersions option determines which version of the OpenSSL library file the driver uses for data
encryption when multiple versions are installed with the product. For example,
when specifying a value of 1.1.1 (AllowedOpenSSLVersions=1.1.1) the driver uses the 1.1.1 version of the library that is installed with the driver.*
The default OpenSSL library version has been updated to 1.0.2r:*
The default OpenSSL library version has been updated to 1.0.2n.*
- The default OpenSSL library version has been updated to 1.0.2k.*
- The default OpenSSL library version has been updated to 1.0.2j.*
- The default OpenSSL library version has been updated to 1.0.2h.*
- The default OpenSSL library version has been updated to 1.0.2g.*
- The default OpenSSL library version has been updated to 1.0.2f.
- Support for Kerberos Authentication.
- The new CryptoLibName and SSLLibName connection options allow you to
designate the OpenSSL libraries used when SSL is enabled.
The following Windows platforms have reached the end of their product lifecycle
and are no longer supported by the driver*:
- Windows 8.0 (versions 8.1 and higher are still supported)
- Windows Vista (all versions)
- Windows XP (all versions)
- Windows Server 2003 (all versions)
- Certified with Red Hat Enterprise 7.0
- Certified with CentOS Linux 7.0
- Certified with Oracle Linux 7.0
- 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
- 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.
- The new Unbounded Numeric Precision connection option allows you to
define the precision for unbounded NUMERIC columns described
within the column, parameter, result set, or table metadata.
- The new Unbounded Numeric Scale connection option allows you to
define the scale for unbounded NUMERIC columns described within
the column, parameter, result set, or table metadata.
- Certified with Windows 8.1
The new KeepAlive connection option allows you to
use TCP Keep Alive to maintain idle TCP connections.
- Certified with CentOS Linux 4.x, 5.x, and 6.x
- Certified with Oracle Linux 4.x, 5.x, and 6.x
The EncryptionMethod connection option now supports Request SSL
functionality. When Request SSL is enabled, login requests and data are
encrypted if the server is configured for SSL. If the server is not
configured for SSL, an unencrypted connection is established.
- Certified with Oracle Solaris 11.1
- Certified with Red Hat 6.3
- Certified with Windows 8 and Windows Server 2012
