The PL/perl and PL/Tcl implementations in PostgreSQL 7.4 before 7.4.30, 8.0 before 8.0.26, 8.1 before 8.1.22, 8.2 before 8.2.18, 8.3 before 8.3.12, 8.4 before 8.4.5, and 9.0 before 9.0.1 do not properly protect script execution by a different SQL user identity within the same session, which allows remote authenticated users to gain privileges via crafted script code in a SECURITY DEFINER function, as demonstrated by (1) redefining standard functions or (2) redefining operators, a different vulnerability than CVE-2010-1168, CVE-2010-1169, CVE-2010-1170, and CVE-2010-1447.

PostgreSQL functions implemented in Perl or TCL shared a global state even across different user user ids. A user could therefore influence functions of other users in an unexpected or even malicious way (CVE-2010-3433).

According to the version of one or more Juniper NSM servers running on the remote host, it is potentially vulnerable to multiple vulnerabilities, the worst of which may allow an authenticated user to trigger a denial of service condition or execute arbitrary code.

The remote Oracle Linux 5 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2010-0742 advisory.

    - Update to PostgreSQL 8.1.22, for various fixes described at       http://www.postgresql.org/docs/8.1/static/release.html       including the fix for CVE-2010-3433     Resolves: #639931

    postgresql84:

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The version of PostgreSQL installed on the remote host is 7.4 prior to 7.4.30, 8.0 prior to 8.0.26, 8.1 prior to 8.1.22, 8.2 prior to 8.2.18, 8.3 prior to 8.3.12, 8.4 prior to 8.4.5, or 9.0 prior to 9.0.1.  It therefore is potentially affected by a privilege escalation vulnerability. 

A remote, authenticated attacker could elevate privileges via specially crafted code in a SECURITY DEFINER function.

It was discovered that a user could utilize the features of the PL/Perl andaPL/Tcl languages to modify the behavior of a SECURITY DEFINER functionacreated by a different user. If the PL/Perl or PL/Tcl language was used toaimplement a SECURITY DEFINER function, an authenticated database user couldause a PL/Perl or PL/Tcl script to modify the behavior of that functionaduring subsequent calls in the same session. This would result in theamodified or injected code also being executed with the privileges of theauser who created the SECURITY DEFINER function, possibly leading to privilege escalation.
(CVE-2010-3433)

These updated postgresql packages upgrade PostgreSQL to version 8.4.5.
Refer to the PostgreSQL Release Notes for a list of changes :

If the postgresql service is running, it will be automatically restarted after installing this update.

For Scientific Linux 4, the updated postgresql packages upgrade PostgreSQL to version 7.4.30.

For Scientific Linux 5, the updated postgresql packages upgrade PostgreSQL to version 8.1.22, and the updated postgresql84 packages upgrade PostgreSQL to version 8.4.5.

If the postgresql service is running, it will be automatically restarted after installing this update.

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.

Updated postgresql packages that fix one security issue are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

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. The PostgreSQL SECURITY DEFINER parameter, which can be used when creating a new PostgreSQL function, specifies that the function will be executed with the privileges of the user that created it.

All PostgreSQL users are advised to upgrade to these updated packages, which correct this issue. If the postgresql service is running, it will be automatically restarted after installing this update.

Upgrade base version to v9.0.1 which contains various bug and security fixes.

(CVE-2010-3433)

PostgreSQL was updated to version 8.1.22 which fixes the security issue.

Update to PostgreSQL 8.4.5, for various fixes described at http://www.postgresql.org/docs/8.4/static/release-8-4-5.html including the fix for CVE-2010-3433

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.

Tim Bunce discovered that PostgreSQL, a database server software, does not properly separate interpreters for server-side stored procedures which run in different security contexts. As a result, non-privileged authenticated database users might gain additional privileges.

Note that this security update may impact intended communication through global variables between stored procedures. It might be necessary to convert these functions to run under the plperlu or pltclu languages, with database superuser privileges.

This security update also includes unrelated bug fixes from PostgreSQL 8.3.12.

USN-1002-1 fixed vulnerabilities in PostgreSQL. This update provides the corresponding update for Ubuntu 10.10.

It was discovered that PostgreSQL did not properly enforce permissions within sessions when PL/Perl and PL/Tcl functions or operators were redefined. A remote authenticated attacker could exploit this to execute arbitrary code with permissions of a different user, possibly leading to privilege escalation.

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.
