Multiple Security Vulnerabilities in PostgreSQL Shipped with Solaris 10 May Allow Elevation of Privileges or Denial of Service (DoS) (see details below)

1. Impact

Multiple security vulnerabilities affecting the PostgreSQL software shipped with Solaris 10 may allow a local or remote user who has access to the PostgreSQL server to cause a Denial of Service (DoS) to the PostgreSQL instance or the server it runs on (due to excessive resource consumption), or to gain elevated privileges on the server.

These issues are described in the following documents:

Official PostgreSQL annoucement: http://www.postgresql.org/about/news.905

CVE-2007-3278 at http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3278

2. Contributing Factors

These issues can occur in the following releases:

SPARC Platform

• Solaris 10 PostgreSQL 8.1 without patch 123590-08
  
• Solaris 10 PostgreSQL 8.2 without patch 136998-02
  

x86 Platform

• Solaris 10 PostgreSQL 8.1 without patch 123591-08
  
• Solaris 10 PostgreSQL 8.2 without patch 136999-02
  

Notes:

1. Solaris 8 and 9 do not ship with PostgreSQL and are not impacted by this issue.
2. A user exploiting this vulnerability must have an account on the PostgreSQL server.
3. This issue affects PostgreSQL versions 7.4.x prior to 7.4.19, 8.0.x prior to 8.0.15, 8.1.x prior to 8.1.11 and 8.2.x prior to 8.2.6.
4. Only systems which have PostgreSQL installed and running are impacted by these issues.
5. Both PostgreSQL 8.1 (SUNWpostgr) and 8.2 (packages beginning with SUNWpostgr-82) can be installed at the same time and are separately impacted by these vulnerabilities.

To determine if a version of PostgreSQL is installed, a command such as the following can be used:

    $ pkginfo | grep SUNWpostgr
    system      SUNWpostgr             PostgreSQL 8.1.9 client programs and libraries
    system      SUNWpostgr-82-client   PostgreSQL 8.2 client tools

To determine if PostgreSQL is running on a server, a command such as the following can be run as the user 'postgres' (or the 'root' user):

for PostgreSQL 8.1:

    $ pg_ctl status -D /var/lib/pgsql/data/
    pg_ctl: neither postmaster nor postgres running

for PostgreSQL 8.2:

    $ /usr/postgres/8.2/bin/pg_ctl status -D /var/postgres/8.2/data/
    pg_ctl: server is running (PID: 395)
    /usr/postgres/8.2/bin/postgres -D /var/postgres/8.2/data

or (where applicable):

    $ svcs  postgresql
    STATE          STIME    FMRI
    disabled       19:42:27 svc:/application/database/postgresql:version_81
    online         19:43:03 svc:/application/database/postgresql:version_82

3. Symptoms

There are no predictable symptoms that would indicate these issues have been exploited to gain elevated privileges on the server.

When these issues are exploited to cause a Denial of Service (DoS), system response may be slow and the postgres(1) process may crash, potentially leaving a core file.

4. Workaround

There is no workaround for these issues. Please see the Resolution section below.

5. Resolution

These issues are addressed in the following releases:

SPARC Platform

• Solaris 10 PostgreSQL 8.1 with patch 123590-08 or later
  
• Solaris 10 PostgreSQL 8.2 with patch 136998-02 or later
  

x86 Platform

• Solaris 10 PostgreSQL 8.1 with patch 123591-08 or later
  
• Solaris 10 PostgreSQL 8.2 with patch 136999-02 or later
