Answer

'Hairy' is used informally to mean difficult, dangerous or frightening. For example, a fast descent down a steep winding mountain road might be referred to as 'a bit hairy'.

If someone used it to describe a piece of programming code, I'd presume it meant problematic in some way. Difficult to use or full of bugs, perhaps.
