[GLSA]

Gentoo Linux Security Advisory

Title: PostgreSQL: Multiple vulnerabilities (GLSA 200505-12)
Severity: normal
Exploitable: remote
Date: May 15, 2005
Updated: June 26, 2007
Bug(s): #91231
ID: 200505-12

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: dev-db/postgresql
Vulnerable: < 7.3.10
Vulnerable: < 7.4.7-r2
Vulnerable: < 8.0.2-r1
Unaffected: = 7.3*
Unaffected: = 7.4*
Unaffected: >= 8.0.1-r3 < 8.0.2
Unaffected: >= 8.0.2-r1
Architectures: All supported architectures


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.o
