Comment 5 Tomas Hoger 2015-11-27 22:33:06 UTC 
Further details of these issue were made public.  This issue is not specific to Oracle JDK - OpenJDK 7 is also affected by this issue.

This problem is described as Issue 42 in Security Exploration's SE-2014-02:

http://www.security-explorations.com/en/SE-2014-02-details.html
http://www.security-explorations.com/materials/SE-2014-02-ORACLE.pdf
http://seclists.org/fulldisclosure/2015/Oct/83

The following fix was applied to OpenJDK 7 upstream:

http://hg.openjdk.java.net/jdk7u/jdk7u/jdk/rev/c434c67b8189
http://mail.openjdk.java.net/pipermail/jdk7u-dev/2015-November/010442.html

Note that the issue was not addressed in HotSpot as suggested in the report, but in the DirectMethodHandle implementation.

The original reporter published a new report indicating that their previous root cause analysis was incorrect and that the DirectMethodHandle was the place with the faulty code:

According to the updated report, this issue was corrected in JDK 8 between versions 8u31 and 8u40, hence it was included with updates for the Apr 2015 CPU, updating JDK8 packages to version 8u45.
