Essential security patch released for java-1.6.0-openjdk in Red Hat Enterprise Linux 6 tackling two major vulnerabilities.
Updated java-1.6.0-openjdk packages that fix two security issues are now available for Red Hat Enterprise Linux 6

Solution

Before applying this update, make sure all previously-released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258

Summary

These packages provide the OpenJDK 6 Java Runtime Environment and the OpenJDK 6 Software Development Kit.
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-2013-1486)
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. (CVE-2013-0169)
Note: If the web browser plug-in provided by the icedtea-web package was installed, CVE-2013-1486 could have been exploited without user interaction if a user visited a malicious website.
This erratum also upgrades the OpenJDK package to IcedTea6 1.11.8. Refer to the NEWS file, linked to in the References, for further information.
All users of java-1.6.0-openjdk are advised to upgrade to these updated packages, which resolve these issues. All running instances of OpenJDK Java must be restarted for the update to take effect.
