  <synopsis>

    unprivileged users to gain administrator rights.

  <background>
    <p>
    PostgreSQL is a SQL compliant, open source object-relational database
    management system.

  <description>
    <p>
    PostgreSQL gives public EXECUTE access to a number of character
    conversion routines, but doesn't validate the given arguments
    (CAN-2005-1409). It has also been reported that the contrib/tsearch2
    module of PostgreSQL misdeclares the return value of some functions as
    "internal" (CAN-2005-1410).
    </p>
  </description>
  <impact type="normal">
    <p>
    An attacker could call the character conversion routines with specially
    setup arguments to crash the backend process of PostgreSQL or to
    potentially gain administrator rights. A malicious user could also call
    the misdeclared functions of the contrib/tsearch2 module, resulting in
    a Denial of Service or other, yet uninvestigated, impacts.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All PostgreSQL users should update to the latest available version and
    follow the guide at <uri link="http://www.postgresql.org/about/news.315">http://www.postgresql.o
    rg/about/news.315</uri>
