15 - From advisory:
16
17 "By sending a malformed directory name it is possible to trigger an
18 error condition that will make the function return at a point where a
19 global pointer variable is already freed and has not got a new value
20 assigned yet. This will result in a classical double-free() when the
21 next Directory request is handled. With the help of other CVS requests
22 it is possible to either leak some information that could be used to
23 determine the heap position or to execute arbitrary code on systems
24 that are known to be vulnerable to this kind of bugs."
