The full version string for this update release is 1. IANA Data 2017c JDK 8u161 contains IANA time zone data version 2017c. For more information, refer to Timezone Data Versions in the JRE Software. JRE Expiration Date The JRE expires whenever a new release with security vulnerability fixes becomes available.

Critical patch updates, which contain security vulnerability fixes, are announced one year in advance on Critical Patch Updates, Security Alerts and Third Party Bulletin. JRE will provide additional warnings and reminders to users to update to the newer version. For more information, see JRE Expiration Date. Add additional IDL stub type checks to org. ORBstring_to_object method  Applications that either explicitly or implicitly call org.

IDL stub type involved in the ORB::string_to_object call flow, should specify additional IDL stub type checking. If the system property is set, its value overrides the corresponding property defined in the java. This change will affect JSSE connections as well as applications built on JCE. Algorithms” security property in the java. This change updates the JDK providers to use 2048 bits as the default key size for DSA instead of 1024 bits when applications have not explicitly initialized the java. If compatibility issues arise, existing applications can set the system property jdk. The previous behavior of this method can be re-enabled by setting the value of the jdk.

The issue with this code is that it is unspecified how the provider should derive a secret key from the output of the Diffie-Hellman operation. There are several options for how this key derivation function can work, and each of these options has different security properties. For example, the key derivation function may bind the secret key to some information about the context or the parties involved in the key agreement. Diffie-Hellman output, which can be used with an appropriate key derivation function to produce a secret key. Implement the key derivation function from an appropriate standard. For example, NIST SP 800-56Ar2 section 5.

8 describes how to derive keys from Diffie-Hellman output. This is a simple key derivation function that may provide adequate security in a typical application. Developers should note that this method provides no protection against the reuse of key agreement output in different contexts, so it is not appropriate for all applications. Also, some additional effort may be required to enforce key size restrictions like the ones in Table 2 of NIST SP 800-57pt1r4. This solution should only be used as a last resort if the application code cannot be modified, or if the application must interoperate with a system that cannot be modified. The “legacy” key derivation function and its security are unspecified.

Jurisdiction Policy files to configure cryptographic algorithm restrictions. Previously, the Policy files in the JDK placed limits on various algorithms. This release ships with both the limited and unlimited jurisdiction policy files, with unlimited being the default. The behavior can be controlled via the new ‘crypto. The RMI Registry filter is relaxed to allow binding arrays of any type The RMI Registry built-in serial filter is modified to check only the array size and not the component type. The maximum array size is increased to 1,000,000.
