Synopsis
========
PostgreSQL is vulnerable to Denial of Service attacks and possibly
allows unprivileged users to gain administrator rights.
Background
==========
PostgreSQL is a SQL compliant, open source object-relational database
management system.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-db/postgresql < 8.0.2-r1 *>= 7.4.7-r2
*>= 8.0.1-r3
>= 8.0.2-r1
Description
===========
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
# emerge --sync
# emerge --ask --oneshot --verbose dev-db/postgresql
