"Several local vulnerabilities have been discovered in PostgreSQL, an
object-relational SQL database. The Common Vulnerabilities and
Exposures project identifies the following problems :

  - CVE-2012-0866
    It was discovered that the permissions of a function
    called by a trigger are not checked. This could result
    in privilege escalation.

  - CVE-2012-0867
    It was discovered that only the first 32 characters of a
    host name are checked when validating host names through
    SSL certificates. This could result in spoofing the
    connection in limited circumstances.

  - CVE-2012-0868
    It was discovered that pg_dump did not sanitise object
    names. This could result in arbitrary SQL command
    execution if a malformed dump file is opened."
