Ubuntu Security Notice USN-5906-1
March 02, 2023

postgresql-12, postgresql-14 vulnerability
==========================================================================

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

- Ubuntu 22.10
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS

Summary:

PostgreSQL could be made to expose sensitive information over the network.

Software Description:
- postgresql-14: Object-relational SQL database
- postgresql-12: Object-relational SQL database

Details:

Jacob Champion discovered that the PostgreSQL client incorrectly handled
Kerberos authentication. If a user or automated system were tricked into
connecting to a malicious server, 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 22.10:
   postgresql-14                   14.7-0ubuntu0.22.10.1
   postgresql-client-14            14.7-0ubuntu0.22.10.1

Ubuntu 22.04 LTS:
   postgresql-14                   14.7-0ubuntu0.22.04.1
   postgresql-client-14            14.7-0ubuntu0.22.04.1

Ubuntu 20.04 LTS:
   postgresql-12                   12.14-0ubuntu0.20.04.1
   postgresql-client-12            12.14-0ubuntu0.20.04.1

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.
