Security vulnerability in PostgreSQL shipped with Solaris may allow a Denial of Service (DoS):

1. Impact

Security vulnerability affecting the PostgreSQL software shipped with Solaris may allow an authenticated PostgreSQL users to cause a Denial of Service (DoS) to the PostgreSQL server (due to stack consumption).

This issue is described in the following documents:

Official PostgreSQL announcement at:

• http://www.postgresql.org/about/news.1065

CVE-2009-0922 at:

• http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-0922
  

2. Contributing Factors

This issue can occur in the following releases:

SPARC Platform

• Solaris 10 PostgreSQL 8.1 without patch 123590-10
• Solaris 10 PostgreSQL 8.2 without patch 136998-06
  
• Solaris 10 PostgreSQL 8.3 without patch 138826-04
  
• OpenSolaris PostgreSQL 8.1 based upon builds snv_01 through snv_109
• OpenSolaris PostgreSQL 8.2 based upon builds snv_81 through snv_111
• OpenSolaris PostgreSQL 8.3 based upon builds snv_87 through snv_111
  

x86 Platform

• Solaris 10 PostgreSQL 8.1 without patch 123591-10
• Solaris 10 PostgreSQL 8.2 without patch 136999-06
  
• Solaris 10 PostgreSQL 8.3 without patch 138827-04
  
• OpenSolaris PostgreSQL 8.1 based upon builds snv_01 through snv_109
• OpenSolaris PostgreSQL 8.2 based upon builds snv_81 through snv_111
• OpenSolaris PostgreSQL 8.3 based upon builds snv_87 through snv_111
  

Note 1: Solaris 8 and Solaris 9 do not ship with PostgreSQL and are thus not impacted by this issue.

Note 2: A user exploiting this vulnerability must have an account on the PostgreSQL server.

Note 3: This issue affects PostgreSQL versions 7.4.x prior to 7.4.25, 8.0.x prior to 8.0.21, 8.1.x prior to 8.1.17, 8.2.x prior to 8.2.13 and 8.3.x prior to 8.3.7.

Note 4: PostgreSQL 8.1 (SUNWpostgr), 8.2 (packages beginning with SUNWpostgr-82) and 8.3 (packages beginning with SUNWpostgr-83)  can be installed at the same time and are separately impacted by this vulnerability.

To determine if a version of PostgreSQL is installed, the following command 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, the following command 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)

for PostgreSQL 8.3:

    $ /usr/postgres/8.3/bin/pg_ctl status -D /var/postgres/8.3/data/
    pg_ctl: server is running (PID: 395)

or (where applicable):

    $ svcs -a | grep postgresql
    disabled       17:12:37 svc:/application/database/postgresql_83:default_32bit
    disabled       17:12:37 svc:/application/database/postgresql:version_82
    disabled       17:12:37 svc:/application/database/postgresql:version_82_64bit
    online         17:13:05 svc:/application/database/postgresql_83:default_64bit

3. Symptoms

If the described issue has been 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 this issue. Please see the Resolution section below.
