postgresql-14, postgresql-16, postgresql-17 vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 25.10
- Ubuntu 25.04
- Ubuntu 24.04 LTS
- Ubuntu 22.04 LTS

Summary:

Several security issues were fixed in PostgreSQL.

Software Description:
- postgresql-17: Object-relational SQL database
- postgresql-16: Object-relational SQL database
- postgresql-14: Object-relational SQL database

Details:

Jelte Fennema-Nio discovered that the PostgreSQL CREATE STATISTICS command
did not correctly check for schema CREATE privileges. An authenticated
attacker could possibly use this issue to create a denial of service
against other CREATE STATISTICS users. (CVE-2025-12817)

Aleksey Solovev discovered that the PostgreSQL libpq client library
incorrectly handled certain memory operations. A remote attacker could
possibly use this issue to cause libpq to crash, resulting in a denial of
service. (CVE-2025-12818)

Update instructions:

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

Ubuntu 25.10
postgresql-17 17.7-0ubuntu0.25.10.1

Ubuntu 25.04
postgresql-17 17.7-0ubuntu0.25.04.1

Ubuntu 24.04 LTS
postgresql-16 16.11-0ubuntu0.24.04.1

Ubuntu 22.04 LTS

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.
