The only way to get a correct answer is to raise a TAC Case. The information found in the Security Bulletin and the Bug ID are, for a lack of a better word, joke.
NOTE:
I can understand anyone reading this Security Bulletin would be thoroughly stymied.
Ok, so the Security Bulletin points to a bug, CSCvk71355. The bug states on the bottom the affected platform to be an End-of-Support 2600 router. The IOS, 15.2(4)E, does not make any sense either.
