USN-5906-1: PostgreSQL vulnerability

Releases

• Ubuntu 22.10
• Ubuntu 22.04 LTS
• Ubuntu 20.04 LTS

Packages

• postgresql-12 - Object-relational SQL database
• postgresql-14 - 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

• postgresql-14 - 14.7-0ubuntu0.22.04.1
• postgresql-client-14 - 14.7-0ubuntu0.22.04.1

Ubuntu 20.04

• 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.
