Any disabled mechanism will be ignored if it is specified in the mechanisms argument of Sasl.createSaslClient or the mechanism argument of Sasl.createSaslServer. The default value for this security property is empty, which means that no mechanisms are disabled out-of-the-box. The full version string for this update release is 1.7.0_251-b08 (where “b” means “build”).

The dns_lookup_realm setting in Kerberos’ krb5.conf file is by default false. The jdk.tls.client.protocols system property is now available with the release of JDK 7u95. This property was originally introduced in JDK 8 and behaves in the same way. All our BPR releases are configured with Java Auto Update disabled as default unless otherwise mentioned. This enhancement provides a way to specify more granular levels for the GC verification enabled using the VerifyBeforeGC, VerifyAfterGC, and VerifyDuringGC diagnostic options. It introduces a new diagnostic option VerifySubSet with which one can specify the subset of the memory system that should be verified.

Java 13 updates

If a buffer overrun is encountered the system will write the message “stack smashing detected” and the program will exit. Please note that fixes from prior BPR (7u211 b32) are included in this version. The jarsigner tool now shows more information about the lifetime of a timestamped JAR. New warning and error messages are displayed when a timestamp has expired or is expiring within one year. Prior to this fix, Windows Server 2019 was recognized as “Windows Server 2016”, which produced incorrect values in the os.name system property and the hs_err_pid file.

If this filter is configured, the JCEKS KeyStore uses it during the deserialization of the encrypted Key object stored inside a SecretKeyEntry. If it is not configured or if the filter result is UNDECIDED https://remotemode.net/ (for example, none of the patterns match), then the filter configured by jdk.serialFilter is consulted. Note that the actual use of enabled cipher suites is restricted by algorithm constraints.

Java™ SE Development Kit 7, Update 271 (JDK 7u

A new security property, jdk.tls.legacyAlgorithms, is added to define the legacy algorithms in Oracle JSSE implementation. The ephemeral DH key size now defaults to 1024 bits during SSL/TLS handshaking in the SunJSSE provider. A new system property, “jdk.tls.ephemeralDHKeySize”, is defined to customize the ephemeral DH key sizes. This can be set to “legacy” if the older JDK behavior (DH keysize of 768 bits) is desired.

These names correspond to the closure of class names that are expected by the server when deserializing credentials. For instance, if the expected credentials were a List, then the closure would constitute all the concrete classes that should be expected in the serial form of a list of Strings. The requirement to have the Authority Key Identifier (AKID) and Subject Key Identifier (SKID) fields matching when building X509 certificate chains has been modified for some cases.

The following sections summarize changes made in all Java SE 7u131 BPR releases. The following sections summarize changes made in all Java SE 7u141 BPR releases. The following sections summarize changes made in all Java SE 7u151 BPR releases.

The full version string for this update release is 1.7.0_161-b13 (where “b” means “build”). The RMI Registry built-in serial filter is modified to check only the array size and not the component type. Array sizes greater than the maxarray limit will be rejected and otherwise will be allowed. In 7u171, the RSA implementation in the SunRsaSign provider will reject any RSA public key that has an exponent that is not in the valid range as defined by PKCS#1 version 2.2. This change will affect JSSE connections as well as applications built on JCE.

C) Set the jdk.crypto.KeyAgreement.legacyKDF system property to “true”. This will restore the previous behavior of this KeyAgreement service. 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 java 7 certifications “legacy” key derivation function and its security are unspecified. The PKCS12 KeyStore implementation has been enhanced to support storage of secret keys and trusted certificates. This allows complete migration of existing JKS and JCEKS KeyStores to PKCS12 using the importkeystore option of the keytool utility.

In case of compatibility issues, an application may disable negotiation of this extension by setting the System Property jdk.tls.useExtendedMasterSecret to false in the JDK. By setting the System Property jdk.tls.allowLegacyResumption to false, an application can reject abbreviated handshaking when the session hash and extended master secret extension is not negotiated. By setting the System Property jdk.tls.allowLegacyMasterSecret to false, an application can reject connections that do not support the session hash and extended master secret extension. 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. This JRE (version 7u221) will expire with the release of the next critical patch update scheduled for July 16, 2019.
