There is no CVE ID for the CWE-208 issue. Our understanding is that
this issue is, in effect, not reachable in any version of the product.
There is no motivation for an attacker to make timing calculations.

In other words, CVE-2014-4156 exists because of a conclusion that the
vendor apparently does not want to offer this type of "misspelled
their account identifier" information.
