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.

CVE-2013-0442, CVE-2013-0445, CVE-2013-0441, CVE-2013-1475, CVE-2013-1476, CVE-2013-0429, CVE-2013-0450, CVE-2013-0425, CVE-2013-0426, CVE-2013-0428

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

CVE-2013-1478, CVE-2013-1480

Multiple flaws were found in the way image parsers in the 2D and AWT components handled image raster parameters. A specially-crafted image could cause Java Virtual Machine memory corruption and, possibly, lead to arbitrary code execution with the virtual machine privileges.

CVE-2013-0432

A flaw was found in the AWT component's clipboard handling code. An untrusted Java application or applet could use this flaw to access clipboard data, bypassing Java sandbox restrictions.

CVE-2013-0435

The default Java security properties configuration did not restrict access to certain com.sun.xml.internal packages. An untrusted Java application or applet could use this flaw to access information, bypassing certain Java sandbox restrictions. This update lists the whole package as restricted.

CVE-2013-0427, CVE-2013-0433, CVE-2013-0434

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

CVE-2013-0424

It was discovered that the RMI component's CGIHandler class used user inputs in error messages without any sanitization. An attacker could use this flaw to perform a cross-site scripting (XSS) attack.

CVE-2013-0440

It was discovered that the SSL/TLS implementation in the JSSE component did not properly enforce handshake message ordering, allowing an unlimited number of handshake restarts. A remote attacker could use this flaw to make an SSL/TLS server using JSSE consume an excessive amount of CPU by continuously restarting the handshake.

CVE-2013-0443

It was discovered that the JSSE component did not properly validate Diffie-Hellman public keys. An SSL/TLS client could possibly use this flaw to perform a small subgroup attack.

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-2013-1486

An improper permission check issue was discovered in the JMX component in OpenJDK. An untrusted Java application or applet could use this flaw to bypass Java sandbox restrictions.

CVE-2013-0169

It was discovered that OpenJDK leaked timing information when decrypting TLS/SSL protocol encrypted records when CBC-mode cipher suites were used. A remote attacker could possibly use this flaw to retrieve plain text from the encrypted packets by using a TLS/SSL server as a padding oracle.

BZ#751203

Previously, after updating OpenJDK to java-1.6.0-openjdk-1.6.0.0-1.40.1.9.10.el6_1, the Java Remote Object Registry (rmiregistry) started only if run with the java.rmi.server.codebase argument, otherwise the registry start failed. This update fixes the regression and the registry can be started without the argument as expected.

BZ#767537

Channel binding for the Kerberos protocol was implemented incorrectly and OpenJDK did not process Kerberos GSS (General Security Services) contexts which did not have incoming channel binding. This resulted in interopability problems with Internet Explorer on Windows Server 2008. With this update, OpenJDK handles unset channel binding correctly and processes Kerberos GSS contexts as expected.

BZ#804632

The SystemTap script translator (stap) run with jstack() systemtap support could terminate with an error similar to the following:

ERROR: kernel read fault at 0x0000000000000018 (addr) near identifier '@cast' at /usr/share/systemtap/tapset/x86_64/jstack.stp:362:29

This update improves the jstack code including, for example, the constant definition and error handling, and the stap script with jstack now works more reliably.

BZ#805936, BZ#807324

This update fixes multiple problems that occurred when using signed jar files.

BZ#751410

Support for huge pages was added.
