Explore critical enhancements in Java Runtime for Red Hat Enterprise Linux, focusing on security vulnerabilities and necessary updates to safeguard systems
Updated java-1.7.0-openjdk packages that fix several 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 7 Java Runtime Environment and the OpenJDK 7 Software Development Kit.
Multiple improper permission check issues were discovered in the Beans, Libraries, Swing, and JMX components in OpenJDK. An untrusted Java application or applet could use these flaws to bypass Java sandbox restrictions. (CVE-2012-5086, CVE-2012-5087, CVE-2012-5088, CVE-2012-5084, CVE-2012-5089)
The default Java security properties configuration did not restrict access to certain com.sun.org.glassfish packages. An untrusted Java application or applet could use these flaws to bypass Java sandbox restrictions. This update lists those packages as restricted. (CVE-2012-5076, CVE-2012-5074)
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-2012-5068, CVE-2012-5071, CVE-2012-5069, CVE-2012-5073, CVE-2012-5072)
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-2012-5079)
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-2012-5081)
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 these flaws to disclose sensitive information. (CVE-2012-5070, CVE-2012-5075)
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-2012-4416)
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-2012-5077)
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-2012-3216)
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-2012-5085)
This erratum also upgrades the OpenJDK package to IcedTea7 2.3.3. Refer to the NEWS file, linked to in the References, for further information.
All users of java-1.7.0-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.
