CentOS 4 / 5 : postgresql (CESA-2008:0038)

high Nessus Plugin ID 29933

Synopsis

The remote CentOS host is missing one or more security updates.

Description

Updated postgresql packages that fix several security issues are now available for Red Hat Enterprise Linux 4 and 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). 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 7.4.19 and 8.1.11, and resolve these issues.

Solution

Update the affected postgresql packages.
