Description

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.
