Crucial patch for java-1.6.0-openjdk on Red Hat Linux released to mitigate various vulnerabilities and enhance overall system protection.
An update for java-1.6.0-openjdk is now available for Red Hat Enterprise Linux 5, Red Hat Enterprise Linux 6, and Red Hat Enterprise Linux 7

Solution

For details on how to apply this update, which includes the changes described in this advisory, refer to:

https://access.redhat.com/articles/11258

All running instances of OpenJDK Java must be restarted for this update to take effect.

Summary

The java-1.6.0-openjdk packages provide the OpenJDK 6 Java Runtime Environment and the OpenJDK 6 Java Software Development Kit.
Security Fix(es):
* An insufficient bytecode verification flaw was discovered in the Hotspot component in OpenJDK. An untrusted Java application or applet could use this flaw to completely bypass Java sandbox restrictions. (CVE-2016-3606)
* Multiple denial of service flaws were found in the JAXP component in OpenJDK. A specially crafted XML file could cause a Java application using JAXP to consume an excessive amount of CPU and memory when parsed. (CVE-2016-3500, CVE-2016-3508)
* Multiple flaws were found in the CORBA and Hotsport components in OpenJDK. An untrusted Java application or applet could use these flaws to bypass certain Java sandbox restrictions. (CVE-2016-3458, CVE-2016-3550)
