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).
Impact
======
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.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All PostgreSQL users should update to the latest available version and
follow the guide at http://www.postgresql.org/about/news.315
Security is a primary focus of Gentoo Linux and ensuring the
confidentiality and security of our users machines is of utmost
importance to us. Any security concerns should be addressed to
security (at) gentoo (dot) org [email concealed] or alternatively, you may file a bug at
