Red Hat Security Advisory

 

Synopsis: Moderate: postgresql security update

Advisory ID: RHSA-2010:0427-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2010-0427.html

Issue date: 2010-05-19

CVE Names: CVE-2009-4136 CVE-2010-0442 CVE-2010-0733

CVE-2010-1169 CVE-2010-1170

=====================================================================

 

1. Summary:

 

Updated postgresql packages that fix multiple security issues are now

available for Red Hat Enterprise Linux 3.

 

The Red Hat Security Response Team has rated this update as having moderate

security impact. Common Vulnerability Scoring System (CVSS) base scores,

which give detailed severity ratings, are available for each vulnerability

from the CVE links in the References section.

 

2. Relevant releases/architectures:

 

Red Hat Desktop version 3 - i386, x86_64

Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64

Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64

Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64

 

3. Description:

 

PostgreSQL is an advanced object-relational database management system

(DBMS). PL/Perl and PL/Tcl allow users to write PostgreSQL functions in the

Perl and Tcl languages, and are installed in trusted mode by default. In

trusted mode, certain operations, such as operating system level access,

are restricted.

 

A flaw was found in the way PostgreSQL enforced permission checks on

scripts written in PL/Perl. If the PL/Perl procedural language was

registered on a particular database, an authenticated database user running

a specially-crafted PL/Perl script could use this flaw to bypass intended

PL/Perl trusted mode restrictions, allowing them to run arbitrary Perl

scripts with the privileges of the database server. (CVE-2010-1169)

 

Red Hat would like to thank Tim Bunce for responsibly reporting the

CVE-2010-1169 flaw.

 

A flaw was found in the way PostgreSQL enforced permission checks on

scripts written in PL/Tcl. If the PL/Tcl procedural language was registered

on a particular database, an authenticated database user running a

specially-crafted PL/Tcl script could use this flaw to bypass intended

PL/Tcl trusted mode restrictions, allowing them to run arbitrary Tcl

scripts with the privileges of the database server. (CVE-2010-1170)

 

A buffer overflow flaw was found in the way PostgreSQL retrieved a

substring from the bit string for BIT() and BIT VARYING() SQL data types.

An authenticated database user running a specially-crafted SQL query could

use this flaw to cause a temporary denial of service (postgres daemon

crash) or, potentially, execute arbitrary code with the privileges of the

database server. (CVE-2010-0442)

 

An integer overflow flaw was found in the way PostgreSQL used to calculate

the size of the hash table for joined relations. An authenticated database

user could create a specially-crafted SQL query which could cause a

temporary denial of service (postgres daemon crash) or, potentially,

execute arbitrary code with the privileges of the database server.

(CVE-2010-0733)

 

PostgreSQL improperly protected session-local state during the execution of

an index function by a database superuser during the database maintenance

operations. An authenticated database user could use this flaw to elevate

their privileges via specially-crafted index functions. (CVE-2009-4136)

 

All PostgreSQL users are advised to upgrade to these updated packages,

which contain backported patches to correct these issues. Running

PostgreSQL instances must be restarted ("service rhdb restart") for this

update to take effect.

 

4. Solution:

 

Before applying this update, make sure all previously-released errata

relevant to your system have been applied.
