    Ubuntu Security Notice USN-3818-1
    November 14, 2018
    
    postgresql-10 vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 18.10
    - Ubuntu 18.04 LTS
    
    Summary:
    
    PostgreSQL could be made to run SQL statements as the administrator.
    
    Software Description:
    - postgresql-10: Object-relational SQL database
    
    Details:
    
    It was discovered that PostgreSQL incorrectly handled certain trigger
    definitions when running pg_upgrade or pg_dump. A remote attacker could
    possibly use this issue to execute arbitrary SQL statements with superuser
    privileges.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 18.10:
      postgresql-10                   10.6-0ubuntu0.18.10.1
    
    Ubuntu 18.04 LTS:
      postgresql-10                   10.6-0ubuntu0.18.04.1
    
    This update uses a new upstream release, which includes additional bug
    fixes. After a standard system update you need to restart PostgreSQL to
    make all the necessary changes.
