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: SQL injection in pg_createsubscriber allows arbitrary SQL execution as superuser (CVE-2026-6476) * postgresql: PostgreSQL: Arbitrary code execution via integer wraparound in tsvector and tsquery functions (CVE-2026-14662) * postgresql: PostgreSQL: Arbitrary code execution via untrusted data inclusion in pg_dump (CVE-2026-18408) * postgresql: PostgreSQL psql: Arbitrary command execution via untrusted data in COPY FROM STDIN (CVE-2026-6464) * postgresql: PostgreSQL: Arbitrary code execution via logical decoding plugin (CVE-2026-6471) * postgresql: PostgreSQL: Arbitrary code execution via type confusion with "internal" arguments (CVE-2026-14680) * postgresql: PostgreSQL: Arbitrary code execution via heap buffer overflow in regexp (CVE-2026-14664) * postgresql: pltcl: plperl: PostgreSQL: Arbitrary code execution in 32-bit pltcl and plperl (CVE-2026-14677) * postgresql-fuzzystrmatch: PostgreSQL fuzzystrmatch: Arbitrary code execution via int…

BELL-CVE-2026-14677

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

BIT-postgresql-2026-14677 — PostgreSQL 32-bit pltcl and plperl undersize allocations, via integer wraparound

Affected: Bitnami: postgresql

Integer wraparound in PostgreSQL 32-bit builds of pltcl and plperl allows an object creator to cause the server to undersize an allocation and write out-of-bounds via crafted function bodies. This may execute arbitrary code as the operating system user running the database. CVE-2026-6473 had fixed similar problems. Versions before PostgreSQL 18.6, 17.11, 16.15, 15.19, and 14.24 are affected.

OESA-2026-3420 — postgresql security update

Affected: openEuler:24.03-LTS-SP4: postgresql

PostgreSQL is an advanced Object-Relational database management system (DBMS). The base postgresql package contains the client programs that you&apos;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):

Integer wraparound in PostgreSQL tsvector and tsquery data type functions allows an unprivileged database user to cause the server to undersize an allocation and write out-of-bounds, via crafted large inputs. This may execute arbitrary code as the operating system user running the database. These types are typically sourced from application logic, not taken from the application's user. Hence, application users attacking the database, through the application as a conduit, are unlikely. CVE-2026-6473 had fixed similar problems. Versions before PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24 are affected.(CVE-2026-14662)

Cleartext storage in PostgreSQL pgcrypto disabled ciphers allows a user to recover cleartext, via direct observation of the faulty ciphertext. The OpenSSL version and OpenSSL configuration determine the disabled ciphers. If the application accepts encrypted data as input, decryption will succeed even with the wrong key. This in turn loses the…

WID-SEC-W-2026-2844 — PostgreSQL: Mehrere Schwachstellen

Ein Angreifer kann mehrere Schwachstellen in PostgreSQL ausnutzen, um beliebigen Programmcode auszuführen, SQL-Injection-Angriffe durchzuführen, Sicherheitsmaßnahmen zu umgehen, Daten offenzulegen oder zu manipulieren oder Denial-of-Service-Zustände herbeizuführen.
