Description (partial)

Tracking Area Update rejects with "illegal ME",  due to Security Mode Command  failure coming from the UE in the NAS . This 'illegal ME' from the MME triggers an unwanted situation at the UE, which is unacceptable.

MME running R14.0 (50176), where this fix is not present. Then issue can be seen.
