    of an unsanitized user field of the Authorization header for HTTP Basic Authentication,
    which is mishandled during a _viewlog operation

  - A buffer over-read in Util_urlDecode allows a remote authenticated attacker
    to retrieve the contents of adjacent memory via manipulation of GET or POST parameters.
    The attacker can also use this to cause a Denial of Service");
