BZ#729502

Previously, the CCacheInputStream class could not to read Kerberos ticket cache files as it failed to handle the configuration settings stored in the ticket cache file under a special principal name. The configuration credentials are now ignored and the ticket cache is parsed correctly. Also, the initial context token generated by the GSSAPI/SPNEGO plug-in was previously rejected by the MIT Kerberos library due to incorrect data type of the reqFlags and NegTokenInit fields. The fields now use the correct data types.

BZ#808293

A JStack exception was thrown when a program was trying to capture both java and native stacktrace (mixed mode). Safety checks have been added and the problem no longer occurs.

Security Fixes

CVE-2012-1711, CVE-2012-1719

Multiple flaws were discovered in the CORBA (Common Object Request Broker Architecture) implementation in Java. A malicious Java application or applet could use these flaws to bypass Java sandbox restrictions or modify immutable object data.

CVE-2012-1716

It was discovered that the SynthLookAndFeel class from Swing did not properly prevent access to certain UI elements from outside the current application context. A malicious Java application or applet could use this flaw to crash the Java Virtual Machine, or bypass Java sandbox restrictions.

CVE-2012-1713

Multiple flaws were discovered in the font manager's layout lookup implementation. A specially-crafted font file could cause the Java Virtual Machine to crash or, possibly, execute arbitrary code with the privileges of the user running the virtual machine.

CVE-2012-1723, CVE-2012-1725

Multiple flaws were found in the way the Java HotSpot Virtual Machine verified the bytecode of the class file to be executed. A specially-crafted Java application or applet could use these flaws to crash the Java Virtual Machine, or bypass Java sandbox restrictions.

CVE-2012-1724

It was discovered that the Java XML parser did not properly handle certain XML documents. An attacker able to make a Java application parse a specially-crafted XML file could use this flaw to make the XML parser enter an infinite loop.

CVE-2012-1718

It was discovered that the Java security classes did not properly handle Certificate Revocation Lists (CRL). CRL containing entries with duplicate certificate serial numbers could have been ignored.

CVE-2012-1717

It was discovered that various classes of the Java Runtime library could create temporary files with insecure permissions. A local attacker could use this flaw to gain access to the content of such temporary files.

Security Fixes

CVE-2012-1682

It was discovered that the Beans component in OpenJDK did not perform permission checks properly. An untrusted Java application or applet could use this flaw to use classes from restricted packages, allowing it to bypass Java sandbox restrictions.

CVE-2012-0547

A hardening fix was applied to the AWT component in OpenJDK, removing functionality from the restricted SunToolkit class that was used in combination with other flaws to bypass Java sandbox restrictions.

Security Fixes

CVE-2012-5086, CVE-2012-5084, CVE-2012-5089

Multiple improper permission check issues were discovered in the Beans, Swing, and JMX components in OpenJDK. An untrusted Java application or applet could use these flaws to bypass Java sandbox restrictions.

CVE-2012-5068, CVE-2012-5071, CVE-2012-5069, CVE-2012-5073, CVE-2012-5072

Multiple improper permission check issues were discovered in the Scripting, JMX, Concurrency, Libraries, and Security components in OpenJDK. An untrusted Java application or applet could use these flaws to bypass certain Java sandbox restrictions.

CVE-2012-5079

It was discovered that java.util.ServiceLoader could create an instance of an incompatible class while performing provider lookup. An untrusted Java application or applet could use this flaw to bypass certain Java sandbox restrictions.

CVE-2012-5081

It was discovered that the Java Secure Socket Extension (JSSE) SSL/TLS implementation did not properly handle handshake records containing an overly large data length value. An unauthenticated, remote attacker could possibly use this flaw to cause an SSL/TLS server to terminate with an exception.

CVE-2012-5075

It was discovered that the JMX component in OpenJDK could perform certain actions in an insecure manner. An untrusted Java application or applet could possibly use this flaw to disclose sensitive information.

CVE-2012-4416

A bug in the Java HotSpot Virtual Machine optimization code could cause it to not perform array initialization in certain cases. An untrusted Java application or applet could use this flaw to disclose portions of the virtual machine's memory.

CVE-2012-5077

It was discovered that the SecureRandom class did not properly protect against the creation of multiple seeders. An untrusted Java application or applet could possibly use this flaw to disclose sensitive information.

CVE-2012-3216

It was discovered that the java.io.FilePermission class exposed the hash code of the canonicalized path name. An untrusted Java application or applet could possibly use this flaw to determine certain system paths, such as the current working directory.

CVE-2012-5085

This update disables Gopher protocol support in the java.net package by default. Gopher support can be enabled by setting the newly introduced property, "jdk.net.registerGopherProtocol", to true.
