(Pound format string vulnerability)

    A format string flaw in the processing of syslog messages was
    discovered and corrected in Pound.
  
Impact :

    This flaw may allow 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. All users are advised to
    upgrade to the latest available version of Pound."
