    The Windows Redirector is used by a Windows client to access files,
    whether local or remote, regardless of the underlying network
    protocols in use. For example, the "Add a Network Place" Wizard or
    the NET USE command can be used to map a network share as a local
    drive, and the Windows Redirector will handle the routing of
    information to and from the network share.

    A security vulnerability exists in the implementation of the
    Windows Redirector on Windows XP because an unchecked buffer is
    used to receive parameter information. By providing malformed data
    to the Windows Redirector, an attacker could cause the system to
    fail, or if the data was crafted in a particular way, could run
    code of the attacker's choice.
