U radu programskog paketa PostgreSQL uočen je niz sigurnosnih propusta. Moguće ih je iskoristiti udaljeno, za pokretanje proizvoljnog programskog koda, izvođenje DoS napada, dobivanje većih ovlasti i zaobilaženje pojedinih ograničenja.

Synopsis
========

Multiple vulnerabilities in the PostgreSQL server and client allow
remote attacker to conduct several attacks, including the execution of
arbitrary code and Denial of Service.

Background
==========

PostgreSQL is an open source object-relational database management
system.

Affected packages
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  dev-db/postgresql              <= 9                   Vulnerable!
  2  dev-db/postgresql-server
                                  < 9.0.5                  *>= 8.2.22 
                                                            *>= 8.4.9 
                                                           *>= 8.3.16 
                                                             >= 9.0.5 
  3  dev-db/postgresql-base       < 9.0.5                  *>= 8.2.22 
                                                            *>= 8.4.9 
                                                           *>= 8.3.16 
                                                             >= 9.0.5 
    -------------------------------------------------------------------
     NOTE: Certain packages are still vulnerable. Users should migrate
           to another package if one is available or wait for the
           existing packages to be marked stable by their
           architecture maintainers.

Description
===========

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.

Resolution
==========

All PostgreSQL 8.2 users should upgrade to the latest 8.2 base version:

  # emerge --sync
  # emerge --ask --oneshot -v ">=dev-db/postgresql-base-8.2.22:8.2"

All PostgreSQL 8.3 users should upgrade to the latest 8.3 base version:

  # emerge --sync
  # emerge --ask --oneshot -v ">=dev-db/postgresql-base-8.3.16:8.3"

All PostgreSQL 8.4 users should upgrade to the latest 8.4 base version:

  # emerge --sync
  # emerge --ask --oneshot -v ">=dev-db/postgresql-base-8.4.9:8.4"

All PostgreSQL 9.0 users should upgrade to the latest 9.0 base version:

  # emerge --sync
  # emerge --ask --oneshot -v ">=dev-db/postgresql-base-9.0.5:9.0"

All PostgreSQL 8.2 server users should upgrade to the latest 8.2 server
version:

  # emerge --sync
  # emerge --ask --oneshot -v ">=dev-db/postgresql-server-8.2.22:8.2"

All PostgreSQL 8.3 server users should upgrade to the latest 8.3 server
version:

  # emerge --sync
  # emerge --ask --oneshot -v ">=dev-db/postgresql-server-8.3.16:8.3"

All PostgreSQL 8.4 server users should upgrade to the latest 8.4 server
version:

  # emerge --sync
  # emerge --ask --oneshot -v ">=dev-db/postgresql-server-8.4.9:8.4"

All PostgreSQL 9.0 server users should upgrade to the latest 9.0 server
version:

  # emerge --sync
  # emerge --ask --oneshot -v ">=dev-db/postgresql-server-9.0.5:9.0"

The old unsplit PostgreSQL packages have been removed from portage.
Users still using them are urged to migrate to the new PostgreSQL
packages as stated above and to remove the old package:

  # emerge --unmerge "dev-db/postgresql"
