Debian: Security update for PostgreSQL

Several local vulnerabilities have been discovered in PostgreSQL, an object-relational SQL database. It was discovered that the permissions of a function called by a trigger are not checked. This could result in privilege escalation. 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. 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. Updated packages are available from security.debian.org.
