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.

Updated java-1.6.0-openjdk packages that fix multiple bugs and add various enhancements are now available for Red Hat Enterprise Linux 6.
The java-1.6.0-openjdk packages provide the OpenJDK 6 Java Runtime Environment and the OpenJDK 6 Software Development Kit.
The java-1.6.0-openjdk packages have been upgraded to upstream version 1.11.1, which provides a number of bug fixes and enhancements over the previous version. (BZ#771971)

Bug Fixes

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.

Enhancement

BZ#751410
Support for huge pages was added.
All users of java-1.6.0-openjdk are advised to upgrade to these updated packages, which fix these bugs and add these enhancements.
