Summary

Important: postgresql18 security update

Details

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 integer wraparound (CVE-2026-15742)
postgresql: PostgreSQL: Arbitrary code execution via type confusion in cursor lifecycle (CVE-2026-16239)
postgresql: PostgreSQL: Arbitrary code execution via long POSIX timezone abbreviation (CVE-2026-14669)
postgresql: PostgreSQL: Arbitrary code execution via type confusion in pg_restore_attribute_stats() (CVE-2026-16238)
postgresql: PostgreSQL: Stack buffer overflow via OUT parameter count manipulation (CVE-2026-14679)
postgresql: PostgreSQL: Arbitrary code execution via type confusion in 'refint' module (CVE-2026-14671)
postgresql: PostgreSQL pg_stat_statements: Arbitrary code execution via heap buffer overflow (CVE-2026-14676)
postgresql: PostgreSQL: Arbitrary code execution via plperl tied hash heap buffer overflow (CVE-2026-14670)
postgresql: PostgreSQL: Information disclosure via type confusion in ctid selectivity estimator (CVE-2026-14668)
postgresql: PostgreSQL pg_dump: Arbitrary code execution via crafted transform lists (CVE-2026-19385)
postgresql: PostgreSQL: Privilege escalation via SQL injection in EXTRACT() deparse (CVE-2026-15741)
