        Vulnerability Type:     remote system compromise

Hi Thomas,

I am a little bit confused about the classification of the wordwrap bug.
Since when is a bufferoverflow in a function argument a remote compromise.
Especially when it is in a parameter that is feeded with user input only
in very very very esoteric scripts. It is a local overflow yes, but it will
only overflow if you feed wordwrap with an esoteric line termination
string. And to exploit this bug remotely you do not only need a script
that feeds your userinput to all of wordwraps parameters but you also
need some special formed script so that the heap is perfectly formed
for your exploit to work.

Just my two cents...
