The full version string for this update release is 1. IANA Data 2018e JDK 7u191 contains IANA time zone data version 2018e. 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 Bulletins. JRE will provide additional warnings and reminders to users to update to the newer version.
For more information, see JRE Expiration Date. Removal of Java DB Java DB, also known as Apache Derby, has been removed in this release. Improve LDAP support Endpoint identification has been enabled on LDAPS connections. Such applications may, if they deem appropriate, disable endpoint identification using a new system property: com. Better stack walking New access checks have been added during the object creation phase of deserialization.
This should not affect ordinary uses of deserialization. However, reflective frameworks that make use of JDK-internal APIs may be impacted. The new checks can be disabled if necessary by setting the system property jdk. This must be done by adding the argument -Djdk. Bug Fixes This release contains fixes for security vulnerabilities described in the Oracle Critical Patch Update.

Critical patch updates, which contain security vulnerability fixes, are announced one year in advance on Critical Patch Updates, Security Alerts and Third Party Bulletin. These exceptions are not re-thrown, so the client is not informed that integrity checks have failed. Filter is also supplied, it supersedes the security property value defined here. The filter pattern uses the same format as jdk.
TLS connections in the JDK via the jdk. Locks has been introduced to control the java. Change to Internal Java Package Names in RPM Installers On the Linux platform, the names of JRE and JDK packages provided by Java RPM installers have been changed. On the Linux platform, the names of installation directories of Java products have also been changed. This behavior can be reverted by setting the runtime property sun. Note, this should not be confused with the sun. This release also contains fixes for security vulnerabilities described in the Oracle Critical Patch Update.
For a more complete list of the bug fixes included in this release, see the JDK 7u181 Bug Fixes page. IANA Data 2017c JDK 7u171 contains IANA time zone data version 2017c. To aid interoperability, the Java keystore type JKS now supports keystore compatibility mode by default. This mode enables JKS keystores to access both JKS and PKCS12 file formats.
To disable keystore compatibility mode, set the Security property keystore. New JMX agent property – jmxremote. Definition : Specifies the bind address for the default JMX agent. Add additional IDL stub type checks to org.
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. This is an “opt in” feature and is not enabled by default. If the system property is set, its value overrides the corresponding property defined in the java. However, in previous JDK releases, java. To revert to the previous behavior, set the system property jdk. 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. Refer to that file for more information on this property.
This change will affect JSSE connections as well as applications built on JCE. CRLs using weak algorithms With one exception, keytool will always print a warning if the certificate, certificate request, or CRL it is parsing, verifying, or generating is using a weak algorithm or key. An algorithm or a key is weak if it matches the value of the jdk. 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. The override filter can be used to decrease the limit.
TLS connections in the JDK by the jdk. DSA keys less than 1024 bits have been added to the jdk. Algorithms Security property in the java. This property contains a list of disabled algorithms and key sizes for signed JAR files. If a signed JAR file uses a disabled algorithm or key size less than the minimum length, signature verification operations will ignore the signature and treat the JAR as if it were unsigned.
Running jarsigner -verify -verbose on a JAR file signed with a weak algorithm or key will print more information about the disabled algorithm or key. For example, to check a JAR file named test. To address the issue, the JAR file will need to be re-signed with a stronger key size. Alternatively, the restrictions can be reverted by removing the applicable weak algorithms or key sizes from the jdk. The user can also provide a filter pattern string to the default agent via management. As a result, a new attribute is added to management.
When keytool is operating on a JKS or JCEKS keystore, a warning may be shown that the keystore uses a proprietary format and migrating to PKCS12 is recommended. Java SE 9 changes the JDK’s Transform, Validation and XPath implementations to use the JDK’s system-default parser even when a third party parser is on the classpath. In order to override the JDK system-default parser, applications need to explicitly set the new System property jdk. A setting through the API overrides the System property which in turn overrides that in the jaxp. For a more complete list of the bug fixes included in this release, see the JDK 7u171 Bug Fixes page. IANA Data 2017b JDK 7u161 contains IANA time zone data version 2017b. Windows – There is a non-functional Java icon in the control panel after installing 6u171 or 7u161 Deployment features in 6u171 and 7u161 have been removed.

The deflate functionality in this version causes a compatibility issue with Tomcat v7. This issue is being fixed via JDK-8189789. Demo references in Solaris install documentation Demos were removed from package tar. They will be patched only if the end user has them installed on the system.
The link above is to the Solaris OS Install Directions for the JDK. Default timeouts have changed for FTP URL handler Timeouts used by the FTP URL protocol handler have been changed from infinite to 5 minutes. To revert this behaviour to that of previous releases, the following system properties may be used, sun. This release introduces a new feature whereby the JCE jurisdiction policy files used by the JDK can be controlled via a new Security property. In older releases, JCE jurisdiction files had to be downloaded and installed separately to allow unlimited cryptography to be used by the JDK. The download and install steps are no longer necessary.
To enable unlimited cryptography, one can use the new crypto. Note: On Solaris, it’s recommended that you remove the old SVR4 packages before installing the new JDK updates. JDK release earlier than 6u131, 7u121, 8u111, then you should set the new crypto. JAR signing standards, which were refreshed in 6u131, 7u121, 8u111, and later updates.

JRE 6 and JRE 7 update releases will no longer include deployment technologies Starting with the Oct 2017 Critical Patch Update, updates for JRE 6 and JRE 7 will no longer include the Java Deployment Technologies required for launching Java applications. If an application requires a Java SE 6 or 7 JRE, the Java Deployment technology in JRE 8 release can be used to run such applications. Deployment Rule Set to specify the JRE version to launch specific programs. Collections use serialization filter to limit array sizes Deserialization of certain collection instances will cause arrays to be allocated.
The exact circumstances under which the serialization filter is called, and with what information, is subject to change in future releases. By default, this property will not have a value, and JDK providers will use their own default values. Entries containing an unrecognized algorithm name will be ignored. If the specified default key size is not a parseable decimal integer, that entry will be ignored as well. This legacy implementation will use the same default value as specified by the javadoc in the interface. New defaults for DSA keys in jarsigner and keytool For DSA keys, the default signature algorithm for keytool and jarsigner has changed from SHA1withDSA to SHA256withDSA and the default key size for keytool has changed from 1024 bits to 2048 bits. Users wishing to revert to the previous behavior can use the -sigalg option of keytool and jarsigner and specify SHA1withDSA and the -keysize option of keytool and specify 1024.

JDK 6 and 7 do not support the stronger defaults and will not be able to verify the JAR. If compatibility with earlier releases is important, you can, at your own risk, use the -sigalg option of jarsigner and specify the weaker SHA1withDSA algorithm. If you use a PKCS11 keystore, the SunPKCS11 provider does not support the SHA256withDSA algorithm. The workaround is to use the -sigalg option of keytool and specify SHA1withDSA. See the Conformance section in the Doclet documentation.

IANA Data 2017b JDK 7u151 contains IANA time zone data version 2017b. 1 and higher, detect all JDK 7 Java Plug-in software as out-of-date, even if they are above the security baseline. Plugin-in Settings” and unchecking “Enable Security Protection” in the drop list.
Java Plug-in blocked in Safari versions 10. NOTE: We recommend use of this workaround only if the distributor of the JAR files can “re-sign” the JAR files. CA certificate included by default in Oracle’s JDK is now blocked by default. To implement this restriction and provide more flexibility for configuring your own restrictions, additional features have been added to the jdk.
Algorithms Security Properties in the java. A new constraint named jdkCA, that when set, restricts the algorithm if it is used in a certificate chain that is anchored by a trust anchor that is pre-installed in the JDK cacerts keystore. This condition does not apply to certificate chains that are anchored by other certificates, including those that are subsequently added to the cacerts keystore. Also, note that the restriction does not apply to trust anchor certificates, since they are directly trusted. The restriction does not apply to trust anchor certificates, since they are directly trusted. JAR that is timestamped, it will not be restricted if it is timestamped before the specified date.
If the JAR is timestamped after the specified date, it will be restricted. SSL client certificate chains, and SignedJAR for certificate chains used with signed JARs. JAR is timestamped, it will not be restricted if it is timestamped before the specified date. The syntax is the same as the certpath property, however certificate checking will not be performed by this property.
In that case, applications can either choose to handle the exception or restore old behaviour by setting system property ‘jdk. This release contains fixes for security vulnerabilities described in the Oracle Java SE Critical Patch Update Advisory. For a more complete list of the bug fixes included in this release, see the JDK 7u151 Bug Fixes page. Remove assertions in 8u that were removed by 8056124 in 9. IANA Data 2017a JDK 7u141 contains IANA time zone data version 2017a. This JDK release introduces a new restriction on how MD5 signed JAR files are verified. If the signed JAR file uses MD5, signature verification operations will ignore the signature and treat the JAR as if it were unsigned.
