PostgreSQL before 8.3.7, 8.2.13, 8.1.17, 8.0.21, and 7.4.25 allows remote authenticated users to cause a denial of service (stack consumption and crash) by triggering a failure in the conversion of a localized error message to a client-specified encoding, as demonstrated using mismatched encoding conversion requests.

Date this patch was last updated by Sun : Jan/14/10

From Red Hat Security Advisory 2009:1484 :

Updated postgresql packages that fix two 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).

It was discovered that the upstream patch for CVE-2007-6600 included in the Red Hat Security Advisory RHSA-2008:0038 did not include protection against misuse of the RESET ROLE and RESET SESSION AUTHORIZATION commands. An authenticated user could use this flaw to install malicious code that would later execute with superuser privileges. (CVE-2009-3230)

A flaw was found in the way PostgreSQL handled encoding conversion. A remote, authenticated user could trigger an encoding conversion failure, possibly leading to a temporary denial of service. Note: To exploit this issue, a locale and client encoding for which specific messages fail to translate must be selected (the availability of these is determined by an administrator-defined locale setting).
(CVE-2009-0922)

Note: For Red Hat Enterprise Linux 4, this update upgrades PostgreSQL to version 7.4.26. For Red Hat Enterprise Linux 5, this update upgrades PostgreSQL to version 8.1.18. Refer to the PostgreSQL Release Notes for a list of changes :

http://www.postgresql.org/docs/7.4/static/release.html http://www.postgresql.org/docs/8.1/static/release.html

All PostgreSQL users should upgrade to these updated packages, which resolve these issues. If the postgresql service is running, it will be automatically restarted after installing this update.

CVE-2007-6600

It was discovered that the upstream patch for CVE-2007-6600 included in the Scientific Linux did not include protection against misuse of the RESET ROLE and RESET SESSION AUTHORIZATION commands.

The remote host is affected by the vulnerability described in GLSA-201110-22 (PostgreSQL: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in PostgreSQL. Please       review the CVE identifiers referenced below for details.
  Impact :

    A remote authenticated attacker could send a specially crafted SQL query       to a PostgreSQL server with the 'intarray' module enabled, possibly       resulting in the execution of arbitrary code with the privileges of the       PostgreSQL server process, or a Denial of Service condition. Furthermore,       a remote authenticated attacker could execute arbitrary Perl code, cause       a Denial of Service condition via different vectors, bypass LDAP       authentication, bypass X.509 certificate validation, gain database       privileges, exploit weak blowfish encryption and possibly cause other       unspecified impact.
  Workaround :

    There is no known workaround at this time.

Remote authenticated users could crash the postgresql server by requesting a conversion with an inappropriate encoding.
(CVE-2009-0922)

Remote authenticated users could crash the postgresql server by requesting a conversion with an inappropriate encoding (CVE-2009-0922).

PostgreSQL before 8.3.7, 8.2.13, 8.1.17, 8.0.21, and 7.4.25 allows remote authenticated users to cause a denial of service (stack consumption and crash) by triggering a failure in the conversion of a localized error message to a client-specified encoding, as demonstrated using mismatched encoding conversion requests (CVE-2009-0922).

This update provides a fix for this vulnerability.

It was discovered that PostgreSQL did not properly handle encoding conversion failures. An attacker could exploit this by sending specially crafted requests to PostgreSQL, leading to a denial of service.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Update to PostgreSQL 8.3.7, for various fixes described at http://www.postgresql.org/docs/8.3/static/release-8-3-7.html

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

This version of PostgreSQL is vulnerable to a denial of service when processing malformed SQL statements.  To exploit this flaw, an attacker would need a valid account and the ability to execute custom queries.  Successful exploitation would result in the attacker shutting down the database.
