An information disclosure flaw was found in the way the Java Virtual Machine (JVM) implementation of Java SE 7 as provided by OpenJDK 7 incorrectly initialized integer arrays after memory allocation (in certain circumstances they had nonzero elements right after the allocation). A remote attacker could use this flaw to obtain potentially sensitive information.
The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
