(Pound: Buffer overflow vulnerability)

    Steven Van Acker has discovered a buffer overflow vulnerability in the
    'add_port()' function in Pound.
  
Impact :

    A remote attacker could send a request for an overly long hostname
    parameter, which could lead to the remote execution of arbitrary code
    with the rights of the Pound daemon process (by default, Gentoo uses
    the 'nobody' user to run the Pound daemon).
  
Workaround :

    There is no known workaround at this time."
