Haskell might be prone to denial-of-service attacks. E.g. sending it 
data that cause it to evaluate an infinite data structure.
Of course, any algorithm might run into an endless loop :-)
Still, I'd want to have the results of a strictness analysis attached to 
Haskell software.

That said, Haskell should be a *lot* more safe than C.
Denial-of-service is something that one should take active precautions 
against, but it's still a far cry from the code injection 
vulnerabilities that come with most C software...

Then again, avoiding global state and using a language with garbage 
collection, a strong type discipline and checked pointer dereferencing 
(say: Java, Ruby, Python, whatever) would probably go a far way towards 
safer software, even if it's not an FPL.
