Description Arun Babu Neelicattu 2013-11-18 04:17:06 UTC
It has been identified that it is possible to inject malicious unsigned bytecode into a signed JAR without failing jarsigner verification. This flaw could be exploited in environments where contents of a verified JAR is considered trusted and unpacked for use.

Note that if the signed JAR is used at runtime, with signature intact, a fatal runtime exception is thrown.

The fix was included in OpenJDK, Oracle JDK and IBM JDK updates released to address January 2014 CPU security issues.  Upstream considered it security hardening rather than vulnerability fix.
