| Description: | These packages provide the OpenJDK 6 Java Runtime Environment and the OpenJDK 6 Software Development Kit.
Multiple flaws were discovered in the font layout engine in the 2D component. An untrusted Java application or applet could possibly use these flaws to trigger Java Virtual Machine memory corruption. (CVE-2013-1569, CVE-2013-2383, CVE-2013-2384)
Multiple improper permission check issues were discovered in the Beans, Libraries, JAXP, and RMI components in OpenJDK. An untrusted Java application or applet could use these flaws to bypass Java sandbox restrictions. (CVE-2013-1558, CVE-2013-2422, CVE-2013-1518, CVE-2013-1557)
The previous default value of the java.rmi.server.useCodebaseOnly property permitted the RMI implementation to automatically load classes from remotely specified locations. An attacker able to connect to an application using RMI could use this flaw to make the application execute arbitrary code. (CVE-2013-1537)
Note: The fix for CVE-2013-1537 changes the default value of the property to true, restricting class loading to the local CLASSPATH and locations specified in the java.rmi.server.codebase property. Refer to Red Hat Bugzilla bug 952387 for additional details.
The 2D component did not properly process certain images. An untrusted Java application or applet could possibly use this flaw to trigger Java Virtual Machine memory corruption. (CVE-2013-2420)
It was discovered that the Hotspot component did not properly handle certain intrinsic frames, and did not correctly perform MethodHandle lookups. An untrusted Java application or applet could use these flaws to bypass Java sandbox restrictions. (CVE-2013-2431, CVE-2013-2421)
It was discovered that JPEGImageReader and JPEGImageWriter in the ImageIO component did not protect against modification of their state while performing certain native code operations. An untrusted Java application or applet could possibly use these flaws to trigger Java Virtual Machine memory corruption. (CVE-2013-2429, CVE-2013-2430)
The JDBC driver manager could incorrectly call the toString() method in JDBC drivers, and the ConcurrentHashMap class could incorrectly call the defaultReadObject() method. An untrusted Java application or applet could possibly use these flaws to bypass Java sandbox restrictions. (CVE-2013-1488, CVE-2013-2426)
The sun.awt.datatransfer.ClassLoaderObjectInputStream class may incorrectly invoke the system class loader. An untrusted Java application or applet could possibly use this flaw to bypass certain Java sandbox restrictions. (CVE-2013-0401)
Flaws were discovered in the Network component's InetAddress serialization, and the 2D component's font handling. An untrusted Java application or applet could possibly use these flaws to crash the Java Virtual Machine. (CVE-2013-2417, CVE-2013-2419)
The MBeanInstantiator class implementation in the OpenJDK JMX component did not properly check class access before creating new instances. An untrusted Java application or applet could use this flaw to create instances of non-public classes. (CVE-2013-2424)
It was discovered that JAX-WS could possibly create temporary files with insecure permissions. A local attacker could use this flaw to access temporary files created by an application using JAX-WS. (CVE-2013-2415)
This erratum also upgrades the OpenJDK package to IcedTea6 1.11.10. 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.
