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. For more information on Security Sun Alerts, see Technical Instruction ID 213557.
