Comment: At this stage there is no workaround or solution to these
vulnerabilities. Sun has however listed contributing factors
that must be met in order for a system to be vulnerable, as well
as commands to check whether the affected software is installed
on your system.
Solaris 8 and 9 do not ship with PostgreSQL and are not impacted
by this issue.

Shipped with Solaris 10 May Allow Elevation of Privileges or Denial of
Service (DoS)
Previously Published As: 103197
Bug ID: 6643754, 6643743
Product

SA Document Body
Multiple Security Vulnerabilities in PostgreSQL Shipped with Solaris 10 May All
ow 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:

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 lib
raries
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
