Sendmail is open source, IOS is not.

Knowing where the problem is and knowing how to exploit it are two

If any IOS source code has ever found its way out of cisco since IOS 10.3 (and surely, that must have happened), then it seems reasonable to assume that there are people in the world currently comparing the advisory to the source.
