Unspecified vulnerability in the Java Runtime Environment (JRE) component in Oracle Java SE 7 Update 17 and earlier, and OpenJDK 6 and 7, allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors related to Libraries. NOTE: the previous information is from the April 2013 CPU. Oracle has not commented on claims from another vendor that this issue is related to incorrect invocation of the defaultReadObject method in the ConcurrentHashMap class, which allows remote attackers to bypass the Java sandbox.

Security readout for executives and security teams

This is a 2013 Java runtime vulnerability affecting older Oracle Java SE 7 and OpenJDK 6/7. Sources say remote attackers could impact confidentiality, integrity, and availability. One external claim links it to a Java sandbox bypass, but Oracle did not confirm that technical detail in the CVE record. Exposure is mainly legacy Java installations: Oracle Java SE 7u17 or earlier, OpenJDK 6/7, and related IcedTea or Linux distribution packages that missed 2013 security updates. Treat this as a legacy technology cleanup priority. It is not flagged as actively exploited in the supplied sources, but any remaining affected Java runtime is old, high-impact, and likely outside normal support expectations. Mitigation focus: Apply Oracle April 2013 CPU or relevant Linux distribution Java security updates.; Update affected IcedTea/OpenJDK packages using vendor advisories from 2013.; Remove unsupported Java 6/7 runtimes where business use no longer requires them..
