RELEASE NOTES FOR: 8u141 ==================================================================================================== Notes generated: Sun Dec 01 15:48:54 CET 2024 Hint: Prefix bug IDs with https://bugs.openjdk.org/browse/ to reach the relevant JIRA entry. JAVA ENHANCEMENT PROPOSALS (JEP): None. RELEASE NOTES: security-libs/javax.net.ssl: JDK-8144566: Custom HostnameVerifier enables SNI extension Earlier releases of JDK 8 Updates didn't always send the Server Name Indication (SNI) extension in the TLS ClientHello phase if a custom hostname verifier was used. This verifier is set via the setHostnameVerifier(HostnameVerifier v) method in HttpsURLConnection. The fix ensures the Server Name is now sent in the ClientHello body. See JDK-8144566 for more details. security-libs/java.security: JDK-8176536: Disable SHA-1 TLS Server Certificates Any TLS server certificate chain containing a SHA-1 certificate (end-entity or intermediate CA) and anchored by a root CA certificate included by default in Oracle's JDK is now blocked by default. TLS Server certificate chains that are anchored by enterprise or private CAs are not affected. Only X.509 certificate chains that are validated by the `PKIX` implementation of the `CertPathValidator` and `CertPathBuilder` APIs and the `SunX509` and `PKIX` implementations of the `TrustManagerFactory` API are subject to the restrictions. Third-party implementations of these APIs are directly responsible for enforcing their own restrictions. To implement this restriction and provide more flexibility for configuring your own restrictions, additional features have been added to the `jdk.certpath.disabledAlgorithms` and `jdk.jar.disabledAlgorithms` Security Properties in the java.security file, as follows: - `jdk.certpath.disabledAlgorithms`: Three new constraints have been added to this Security Property: 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. A new constraint named `denyAfter`, that when set, restricts the algorithm if it is used in a certificate chain after the specified date. The restriction does not apply to trust anchor certificates, since they are directly trusted. Also, code signing certificate chains as used in signed JARs are treated specially as follows: - if the certificate chain is used with a signed JAR that is not timestamped, it will be restricted after the specified date - if the certificate chain is used with a signed 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. A new constraint named `usage`, that when set, restricts the algorithm if it is used in a certificate chain for the specified use(s). Three usages are initially supported: `TLSServer` for TLS/SSL server certificate chains, `TLSClient` for TLS/SSL client certificate chains, and `SignedJAR` for certificate chains used with signed JARs. Multiple constraints can be combined to constrain an algorithm when delimited by '&'. For example, to disable SHA-1 TLS Server certificate chains that are anchored by pre-installed root CAs, the constraint is "SHA1 jdkCA & usage TLSServer". - `jdk.jar.disabledAlgorithms`: A new constraint has been added named `denyAfter`, that when set, restricts the algorithm if it is used in a signed JAR after the specified date, as follows: - if the JAR is not timestamped, it will be restricted (treated as unsigned) after the specified date - if the JAR 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. For example, to restrict SHA1 in JAR files signed after January 1st 2018, add the following to the property: "SHA1 denyAfter 2018-01-01". The syntax is the same as the certpath property, however certificate checking will not be performed by this property.
