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.
