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
