Synopsis:          Moderate: Red Hat Application Stack v2.3 security and enhancement update
Advisory ID:       RHSA-2009:1067-01
Product:           Red Hat Application Stack
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2009-1067.html
Issue date:        2009-05-26
CVE Names:         CVE-2008-3963 CVE-2008-4098 CVE-2009-0663 
                   CVE-2009-0922 CVE-2009-1341 
====================================================================
1. Summary:

Red Hat Application Stack v2.3 is now available. This update fixes several
security issues and adds various enhancements.

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 v2 for Enterprise Linux (v.5) - i386, x86_64

3. Description:

Red Hat Application Stack v2.3 is an integrated open source application
stack, that includes Red Hat Enterprise Linux 5 and JBoss Enterprise
Application Platform (EAP). JBoss EAP is provided through the JBoss EAP
channels on the Red Hat Network.

This update fixes the following security issues:

A heap-based buffer overflow flaw was discovered in the perl-DBD-Pg
pg_getline function implementation. If the pg_getline or getline functions
read large, untrusted records from a database, it could cause an
application using these functions to crash or, possibly, execute arbitrary
code. (CVE-2009-0663)

Note: After installing this update, pg_getline may return more data than
specified by its second argument, as this argument will be ignored. This is
consistent with current upstream behavior. Previously, the length limit
(the second argument) was not enforced, allowing a buffer overflow.

A memory leak flaw was found in the perl-DBD-Pg function performing the
de-quoting of BYTEA type values acquired from a database. An attacker able
to cause an application using perl-DBD-Pg to perform a large number of SQL
queries returning BYTEA records, could cause the application to use
excessive amounts of memory or, possibly, crash. (CVE-2009-1341)

MySQL was updated to version 5.0.79, fixing the following security issues:

A flaw was found in the way MySQL handles an empty bit-string literal. A
remote, authenticated attacker could crash the MySQL server daemon (mysqld)
if they used an empty bit-string literal in an SQL statement. This issue
only caused a temporary denial of service, as the MySQL daemon was
automatically restarted after the crash. (CVE-2008-3963)

It was discovered that the Red Hat Security Advisory RHSA-2008:0505, for
Red Hat Application Stack v2.1, provided an incomplete fix for the flaw
where MySQL did not correctly check directories used as arguments for the
DATA DIRECTORY and INDEX DIRECTORY directives. Using this flaw, an
authenticated attacker could elevate their access privileges to tables
created by other database users. Note: This attack does not work on
existing tables. An attacker can only elevate their access to another
user's tables as the tables are created. As well, the names of these
created tables need to be predicted correctly for this attack to succeed.
(CVE-2008-4098)

PostgreSQL was updated to version 8.2.13, fixing the following security
issue:

A flaw was found in the way PostgreSQL handles encoding conversion. A
remote, authenticated user could trigger an encoding conversion failure,
possibly leading to a temporary denial of service. (CVE-2009-0922)

Also, the following packages have been updated:

* httpd to 2.2.11
* mysql-connector-odbc to 3.51.27r695
* perl-DBD-MySQL to 4.010-1.el5s2
* php to 5.2.9
* postgresql-jdbc to 8.2.509
* postgresqlclient81 to 8.1.17

All users should upgrade to these updated packages, which resolve these
issues. Users must restart the individual services, including postgresql,
mysqld, and httpd, for this update to take effect.

4. Solution:

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

This update is available via Red Hat Network. Details on how to use
the Red Hat Network to apply this update are available at

5. Bugs fixed (https://bugzilla.redhat.com/):

462071 - CVE-2008-3963 MySQL: Using an empty binary value leads to server crash
488156 - CVE-2009-0922 postgresql: potential DoS due to conversion functions
497367 - CVE-2009-0663 perl-DBD-Pg: pg_getline buffer overflow
