Indeed. Google has an interesting fix for this. I'll
check if it's been published.

getpwent() is an enumeration function. In order to get the specific
entry for a particular user, you need getpwnam(), not getpwent().

I still don't see why you need to do an enumeration for a new
user. A getpwnam() call on the specific name is all you need
to verify if a new user exists.
What specific application is making the getpwent() call ? Why is it
doing this ?
