Ubuntu Security Notice USN-4282-1
February 18, 2020

postgresql-10, postgresql-11 vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 19.10
- Ubuntu 18.04 LTS


PostgreSQL could allow unintended access to the database.

Software Description:
- postgresql-11: Object-relational SQL database
- postgresql-10: Object-relational SQL database


It was discovered that PostgreSQL incorrectly performed authorization
checks when handling the "ALTER ... DEPENDS ON EXTENSION" sub-commands. A
remote attacker could possibly use this issue to drop any function,
procedure, materialized view, index, or trigger under certain conditions.

Update instructions:

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

Ubuntu 19.10:
  postgresql-11                   11.7-0ubuntu0.19.10.1

Ubuntu 18.04 LTS:
  postgresql-10                   10.12-0ubuntu0.18.04.1

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.
