From Red Hat Security Advisory 2007:0064 :

Updated postgresql packages that fix two security issues are now available for Red Hat Enterprise Linux 3 and 4.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

PostgreSQL is an advanced Object-Relational database management system (DBMS).

A flaw was found in the way the PostgreSQL server handles certain SQL-language functions. An authenticated user could execute a sequence of commands which could crash the PostgreSQL server or possibly read from arbitrary memory locations. A user would need to have permissions to drop and add database tables to be able to exploit this issue (CVE-2007-0555).

A denial of service flaw was found affecting the PostgreSQL server running on Red Hat Enterprise Linux 4 systems. An authenticated user could execute a SQL command which could crash the PostgreSQL server.
(CVE-2006-5540)

Users of PostgreSQL should upgrade to these updated packages containing PostgreSQL version 7.4.16 or 7.3.18, which correct these issues.

Updated postgresql packages that fix several security issues are now available for Red Hat Enterprise Linux 5.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

PostgreSQL is an advanced Object-Relational database management system (DBMS).

Two flaws were found in the way the PostgreSQL server handles certain SQL-language functions. An authenticated user could execute a sequence of commands which could crash the PostgreSQL server or possibly read from arbitrary memory locations. A user would need to have permissions to drop and add database tables to be able to exploit these issues (CVE-2007-0555, CVE-2007-0556).

Several denial of service flaws were found in the PostgreSQL server.
An authenticated user could execute certain SQL commands which could crash the PostgreSQL server (CVE-2006-5540, CVE-2006-5541, CVE-2006-5542).

Users of PostgreSQL should upgrade to these updated packages containing PostgreSQL version 8.1.8 which corrects these issues.

It was discovered that the PostgreSQL database performs insufficient type checking for SQL function arguments, which might lead to denial of service or information disclosure.

This update fixes two vulnerabilities that affect the backend server and can only be exploited by authenticated users to cause a denial-of-service, or maybe to access other tables/databases without authentication. (CVE-2007-0555 CVE-2007-0556)

USN-417-1 fixed several vulnerabilities in the PostgreSQL server.
Unfortunately this update had a regression that caused some valid queries to be aborted with a type error. This update corrects that problem.

We apologize for the inconvenience.

The remote host is affected by the vulnerability described in GLSA-200703-15 (PostgreSQL: Multiple vulnerabilities)

    PostgreSQL does not correctly check the data types of the SQL function     arguments under unspecified circumstances nor the format of the     provided tables in the query planner.
  Impact :

    A remote authenticated attacker could send specially crafted queries to     the server that could result in a server crash and possibly the     unauthorized reading of some database content or arbitrary memory.
  Workaround :

    There is no known workaround at this time.

Jeff Trout discovered that the PostgreSQL server did not sufficiently check data types of SQL function arguments in some cases. A user could then exploit this to crash the database server or read out arbitrary locations of the server's memory, which could be used to retrieve database contents that the user should not be able to see. Note that a user must be authenticated in order to exploit this (CVE-2007-0555).

As well, Jeff Trout also discovered that the query planner did not verify that a table was still compatible with a previously-generated query plan, which could be exploited to read out arbitrary locations of the server's memory by using ALTER COLUMN TYPE during query execution. Again, a user must be authenticated in order to exploit this (CVE-2007-0556).

Update :

The previous update updated PostgreSQL to upstream versions, including 8.1.7 which contained a bug with typemod data types used with check constraints and expression indexes. This regression has been corrected in the new 8.1.8 version that is being provided.

The remote Redhat Enterprise Linux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2007:0064 advisory.

The remote host is running PostgreSQL, an open source relational database.  This version is vulnerable to multiple flaws where an attacker with a valid user account can cause the service to stop or potentially disclose confidential information.  Successful exploitation would result in the system being unavailable to legitimate users or the leakage of confidential data.
