   Solution Type: Sun Alert
   Solution  258808 :   Security Vulnerability in PostgreSQL Shipped with
   Solaris may Allow a Denial of Service (DoS)
   Bug ID: 6817870, 6817871, 6818380

   Product
   Solaris 10
   OpenSolaris

   Date of Workaround Release: 13-May-2009

   SA Document Body
   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
     * Solaris 10 PostgreSQL 8.3
     * 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
     * Solaris 10 PostgreSQL 8.3
     * 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 lib
    raries
    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_32b
    it
    disabled       17:12:37 svc:/application/database/postgresql:version_82
    disabled       17:12:37 svc:/application/database/postgresql:version_82_64b
    it
    online         17:13:05 svc:/application/database/postgresql_83:default_64b
    it

   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.

   5. Resolution

   This issue is addressed in the following releases:
   SPARC Platform
     * Solaris 10 PostgreSQL 8.1 with patch 123590-10 or later
     * OpenSolaris PostgreSQL 8.2 based upon builds snv_111a or later
     * OpenSolaris PostgreSQL 8.3 based upon builds snv_111a or later

   x86 Platform
     * Solaris 10 PostgreSQL 8.1 with patch 123591-10 or later
     * OpenSolaris PostgreSQL 8.2 based upon builds snv_111a or later
     * OpenSolaris PostgreSQL 8.3 based upon builds snv_111a or later

   Note: PostgreSQL 8.1 was removed from OpenSolaris snv_110 onwards.
   A final resolution is pending completion for PostgreSQL 8.2 and
   PostgreSQL 8.3 for Solaris 10.
