==========================================================================
Ubuntu Security Notice USN-4735-1
February 15, 2021

postgresql-12 vulnerability
==========================================================================

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

- Ubuntu 20.10
- Ubuntu 20.04 LTS

Summary:

PostgreSQL could be made to expose sensitive information.

Software Description:
- postgresql-12: Object-relational SQL database

Details:

Heikki Linnakangas discovered that PostgreSQL incorrectly leaked values of
denied columns when handling certain errors. A remote attacker could
possibly use this issue to obtain sensitive information.

Update instructions:

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

Ubuntu 20.10:
  postgresql-12                   12.6-0ubuntu0.20.10.1

Ubuntu 20.04 LTS:
  postgresql-12                   12.6-0ubuntu0.20.04.1

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.
