It was discovered that PostgreSQL could be made to unload and reload an already loaded module by using the LOAD command. A remote authenticated attacker could exploit this to cause a denial of service. This issue did not affect Ubuntu 6.06 LTS. (CVE-2009-3229)

Due to an incomplete fix for CVE-2007-6600, RESET ROLE and RESET SESSION AUTHORIZATION operations were allowed inside security-definer functions. A remote authenticated attacker could exploit this to escalate privileges within PostgreSQL. (CVE-2009-3230)

It was discovered that PostgreSQL did not properly perform LDAP authentication under certain circumstances. When configured to use LDAP with anonymous binds, a remote attacker could bypass authentication by supplying an empty password. This issue did not affect Ubuntu 6.06 LTS. (CVE-2009-3231).

Updated postgresql packages that fix a security issue are now available for Red Hat Enterprise Linux 3.

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-2008:0039 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)

All PostgreSQL users should upgrade to these updated packages, which contain a backported patch to correct this issue. If you are running a PostgreSQL server, the postgresql service must be restarted for this update to take effect.

- Mon Jan 7 2008 Tom Lane <tgl at redhat.com> 8.2.6-1

    - Update to PostgreSQL 8.2.6 to fix CVE-2007-4769,       CVE-2007-4772, CVE-2007-6067, CVE-2007-6600,       CVE-2007-6601

  - Make initscript and pam config files be installed     unconditionally; seems new buildroots don't necessarily     have those directories in place

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.

Several local vulnerabilities have been discovered in PostgreSQL, an object-relational SQL database. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2007-3278     It was discovered that the DBLink module performed     insufficient credential validation. This issue is also     tracked as CVE-2007-6601, since the initial upstream fix     was incomplete.

  - CVE-2007-4769     Tavis Ormandy and Will Drewry discovered that a bug in     the handling of back-references inside the regular     expressions engine could lead to an out of bounds read,     resulting in a crash. This constitutes only a security     problem if an application using PostgreSQL processes     regular expressions from untrusted sources.

  - CVE-2007-4772     Tavis Ormandy and Will Drewry discovered that the     optimizer for regular expression could be tricked into     an infinite loop, resulting in denial of service. This     constitutes only a security problem if an application     using PostgreSQL processes regular expressions from     untrusted sources.

  - CVE-2007-6067     Tavis Ormandy and Will Drewry discovered that the     optimizer for regular expression could be tricked     massive resource consumption. This constitutes only a     security problem if an application using PostgreSQL     processes regular expressions from untrusted sources.

  - CVE-2007-6600     Functions in index expressions could lead to privilege     escalation. For a more in depth explanation please see     the upstream announce available at     http://www.postgresql.org/about/news.905.

The Rocky Linux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the CIQ ciqsa-2026_0478 advisory.

    This advisory aggregates security fixes for the postgresql SRPM in CIQ LTS 9.2. It addresses 34 CVEs:
    CVE-2007-0555, CVE-2025-8714, CVE-2012-2655, CVE-2007-6067, CVE-2012-0867, and 29 more.

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

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