(GNU Radius: Format string vulnerability)

    A format string vulnerability was found in the sqllog function from the
    SQL accounting code for radiusd. That function is only used if one or
    more of the 'postgresql', 'mysql' or 'odbc' USE flags are enabled,
    which is not the default, except for the 'server' 2006.1 and 2007.0
    profiles which enable the 'mysql' USE flag.
  
Impact :

    An unauthenticated remote attacker could execute arbitrary code with
    the privileges of the user running radiusd, which may be the root user.
    It is important to note that there is no default GNU Radius user for
    Gentoo systems because no init script is provided with the package.
  
Workaround :

    There is no known workaround at this time."
