PostgreSQL is an advanced Object-Relational database management system (DBMS). The base postgresql package contains the client programs that you'll need to access a PostgreSQL DBMS server, as well as HTML documentation for the whole system. These client programs can be located on the same machine as the PostgreSQL server, or on a remote machine that accesses a PostgreSQL server over a network connection. The PostgreSQL server can be found in the postgresql-server sub-package.

Security Fix(es):

* postgresql: PostgreSQL pg_trgm heap buffer overflow writes pattern onto server memory (CVE-2026-2007) * postgresql: PostgreSQL oidvector discloses a few bytes of memory (CVE-2026-2003) * postgresql: PostgreSQL missing validation of multibyte character length executes arbitrary code (CVE-2026-2006) * postgresql: PostgreSQL intarray missing validation of type of input to selectivity estimator executes arbitrary code (CVE-2026-2004) * postgresql: PostgreSQL pgcrypto heap buffer overflow executes arbitrary code (CVE-2026-2005)

Heap buffer overflow in PostgreSQL pg_trgm allows a database user to achieve unknown impacts via a crafted input string. The attacker has limited control over the byte patterns to be written, but we have not ruled out the viability of attacks that lead to privilege escalation. PostgreSQL 18.1 and 18.0 are affected.

Ein entfernter, authentisierter oder anonymer Angreifer kann mehrere Schwachstellen in PostgreSQL ausnutzen, um Informationen offenzulegen, beliebigen Code auszuführen und nicht näher bezeichnete Angriffe durchzuführen, was möglicherweise zu einer Ausweitung der Berechtigungen führen kann.
