Security Baselines

The security baselines for the Java Runtime at the time of the release of JDK 11.0.23 are specified in the following table:

Java Family Version Security Baseline (Full Version String)

Keeping the JDK up to Date

Oracle recommends that the JDK is updated with each Critical Patch Update. In order to determine if a release is the latest, the Security Baseline page can be used to determine which is the latest version for each release family.

Critical patch updates, which contain security vulnerability fixes, are announced one year in advance on Critical Patch Updates, Security Alerts and Bulletins. It is not recommended that this JDK (version 11.0.23) be used after the next critical patch update scheduled for July 16, 2024.

Java Management Service, available to all users, can help you find vulnerable Java versions in your systems. Java SE Subscribers and customers running in Oracle Cloud can use Java Management Service to update Java Runtimes and to do further security reviews like identifying potentially vulnerable third party libraries used by your Java programs.

New Features

 Update XML Security for Java to 3.0.3 (JDK-8319124)

The XML Signature implementation has been updated to Santuario 3.0.3. Support for four new SHA-3 based RSA-MGF1 signature methods have been added: SHA3_224_RSA_MGF1, SHA3_256_RSA_MGF1, SHA3_384_RSA_MGF1, and SHA3_512_RSA_MGF1. While these new algorithm URIs are not defined in javax.xml.crypto.dsig.SignatureMethod in the JDK update releases, they may be represented as string literals in order to be functionally equivalent. SHA-3 hash algorithm support was delivered to JDK 9 via JEP 287. Releases earlier than that may use third party security providers.

Additionally, support for the following EdDSA signatures has been added: ED25519 and ED448. While these new algorithm URIs are not defined in javax.xml.crypto.dsig.SignatureMethod in the JDK Update releases, they may be represented as string literals in order to be functionally equivalent. The JDK supports EdDSA since JDK 15. Releases earlier than that may use 3rd party security providers. One other difference is that the JDK still supports the here() function by default. However, we recommend avoiding the use of the here() function in new signatures and replacing existing signatures that use the here() function. Future versions of the JDK will likely disable, and eventually remove, support for this function, as it cannot be supported using the standard Java XPath API. Users can now disable the here() function by setting the security property jdk.xml.dsig.hereFunctionSupported to "false".


Other Notes

 AWT SystemTray API Is Not Supported on Most Linux Desktops (JDK-8322750)

The java.awt.SystemTray API is used for notifications in a desktop taskbar and may include an icon representing an application. On Linux, the Gnome desktop's own icon support in the taskbar has not worked properly for several years due to a platform bug. This, in turn, has affected the JDK's API, which relies upon that.

Therefore, in accordance with the existing Java SE specification, java.awt.SystemTray.isSupported() will return false where ever the JDK determines the platform bug is likely to be present.

The impact of this is likely to be limited since applications always must check for that support anyway. Additionally, some distros have not supported the SystemTray for several years unless the end-user chooses to install non-bundled desktop extensions.

 Added Certainly R1 and E1 Root Certificates (JDK-8321408)

The following root certificates have been added to the cacerts truststore:

+ Certainly

  + certainlyrootr1
    DN: CN=Certainly Root R1, O=Certainly, C=US
+ Certainly
  + certainlyroote1
    DN: CN=Certainly Root E1, O=Certainly, C=US

 Enable XML Signature Secure Validation Mode by Default (JDK-8259801)

The XML Signature secure validation mode has been enabled by default (previously it was not enabled by default unless running with a security manager). When enabled, validation of XML signatures are subject to stricter checking of algorithms and other constraints as specified by the jdk.xml.dsig.secureValidationPolicy security property.

If necessary, and at their own risk, applications can disable the mode by setting the property to Boolean.FALSE with the DOMValidateContext.setProperty() API.
