PostgreSQL is an advanced object-relational database management system (DBMS).

Security Fix(es):

* postgresql: PostgreSQL: Denial of Service via uncontrolled recursion in SSL/GSS negotiation (CVE-2026-6479)

Affected: Alpaquita:23: postgresql15, Alpaquita:25: postgresql17, Alpaquita:stream: postgresql18

Affected: Bitnami: postgresql

Uncontrolled recursion in PostgreSQL SSL and GSS negotiation allows an attacker able to connect to a PostgreSQL AF_UNIX socket to achieve sustained denial of service. If SSL and GSS are both disabled, an attacker can do the same via access to a PostgreSQL TCP socket. Versions before PostgreSQL 18.4, 17.10, 16.14, 15.18, and 14.23 are affected.

PostgreSQL is a powerful, open source object-relational database system that uses and extends the SQL language combined with many features that safely store and scale the most complicated data workloads. This package provides the essential shared library for any PostgreSQL client program or interface. Security Fix(es):

Missing authorization in PostgreSQL CREATE TYPE allows an object creator to hijack other queries that use search_path to find user-defined types, including extension-defined types. That is to say, the victim will execute arbitrary SQL functions of the attacker's choice. Versions before PostgreSQL 18.4, 17.10, 16.14, 15.18, and 14.23 are affected.(CVE-2026-6472)

Integer wraparound in multiple PostgreSQL server features allows an unprivileged database user to cause the server to undersize an allocation and write out-of-bounds. This may execute arbitrary code as the operating system user running the database. In applications that pass gigabyte-scale user inputs to the relevant database functions, the application input provider may achieve a segmentation fault. Versions before PostgreSQL 18.4, 17.10, 16.14, 15.18, and 14.23 are affected.(CVE-2026-6473)

Externally-controlled format string in PostgreSQL timeofday() function allows an attacker to retrieve portions of server memory, via crafted timezone zones. Versions before PostgreSQL 18.4, 17.10, 16.14, 15.18, and 14.23 are affected.(CVE-2026-6474)

Ein Angreifer kann mehrere Schwachstellen in PostgreSQL ausnutzen, um beliebigen Programmcode auszuführen, um einen Denial of Service Angriff durchzuführen, um Informationen offenzulegen, um Dateien zu manipulieren, um einen SQL-Injection Angriff durchzuführen, und um Sicherheitsvorkehrungen zu umgehen.
