Summary:

Several security issues were fixed in PostgreSQL.

Software Description:

- 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)

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
