December 06, 2023

postgresql-12, postgresql-14, postgresql-15 vulnerabilities
==========================================================================

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

- Ubuntu 23.10
- Ubuntu 23.04
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS

Summary:

Several security issues were fixed in PostgreSQL.

Software Description:
- postgresql-15: Object-relational SQL database
- postgresql-14: Object-relational SQL database
- postgresql-12: Object-relational SQL database

Details:

Jingzhou Fu discovered that PostgreSQL incorrectly handled certain unknown
arguments in aggregate function calls. A remote attacker could possibly use
this issue to obtain sensitive information. (CVE-2023-5868)

Pedro Gallegos discovered that PostgreSQL incorrectly handled modifying
certain SQL array values. A remote attacker could use this issue to obtain
sensitive information, or possibly execute arbitrary code. (CVE-2023-5869)

Hemanth Sandrana and Mahendrakar Srinivasarao discovered that PostgreSQL
allowed the pg_signal_backend role to signal certain superuser processes,
contrary to expectations. (CVE-2023-5870)

Update instructions:

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

Ubuntu 23.10:
   postgresql-15                   15.5-0ubuntu0.23.10.1
   postgresql-client-15            15.5-0ubuntu0.23.10.1

Ubuntu 23.04:
   postgresql-15                   15.5-0ubuntu0.23.04.1
   postgresql-client-15            15.5-0ubuntu0.23.04.1

Ubuntu 22.04 LTS:
   postgresql-14                   14.10-0ubuntu0.22.04.1
   postgresql-client-14            14.10-0ubuntu0.22.04.1

Ubuntu 20.04 LTS:
   postgresql-12                   12.17-0ubuntu0.20.04.1
   postgresql-client-12            12.17-0ubuntu0.20.04.1

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.
