USN-3818-1: PostgreSQL vulnerability

14 November 2018

PostgreSQL could be made to run SQL statements as the administrator.




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

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 18.10
Ubuntu 18.04

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.
