Red Hat Security Advisory Synopsis: Moderate: postgresql security update Advisory ID: RHSA-2008:0040-01 Product: Red Hat Application Stack Advisory URL: https://rhn.redhat.com/errata/RHSA-2008-0040.html Issue date: 2008-02-01 CVE Names: CVE-2007-3278 CVE-2007-4769 CVE-2007-4772 CVE-2007-6067 CVE-2007-6600 CVE-2007-6601 =====================================================================
  1. Summary:

Updated postgresql packages that fix several security issues are now available for Red Hat Application Stack v1 and v2.

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

2. Relevant releases/architectures:

Red Hat Application Stack v1 for Enterprise Linux AS (v.4) - i386, x86_64 Red Hat Application Stack v1 for Enterprise Linux ES (v.4) - i386, x86_64 Red Hat Application Stack v2 for Enterprise Linux (v.5) - i386, x86_64

3. Description:

PostgreSQL is an advanced Object-Relational database management system (DBMS). The postgresql packages include the client programs and libraries needed to access a PostgreSQL DBMS server.

Will Drewry discovered multiple flaws in PostgreSQL's regular expression engine. An authenticated attacker could use these flaws to cause a denial of service by causing the PostgreSQL server to crash, enter an infinite loop, or use extensive CPU and memory resources while processing queries containing specially crafted regular expressions. Applications that accept regular expressions from untrusted sources may expose this problem to unauthorized attackers. (CVE-2007-4769, CVE-2007-4772, CVE-2007-6067)

A privilege escalation flaw was discovered in PostgreSQL. An authenticated attacker could create an index function that would be executed with administrator privileges during database maintenance tasks, such as database vacuuming. (CVE-2007-6600)

A privilege escalation flaw was discovered in PostgreSQL's Database Link library (dblink). An authenticated attacker could use dblink to possibly escalate privileges on systems with "trust" or "ident" authentication configured. Please note that dblink functionality is not enabled by default, and can only by enabled by a database administrator on systems with the postgresql-contrib package installed. (CVE-2007-3278, CVE-2007-6601) All postgresql users should upgrade to these updated packages, which include PostgreSQL 8.1.11 and 8.2.6, and resolve these issues.

4. Solution:

Before applying this update, make sure that all previously-released errata relevant to your system have been applied.
