Summary
Important: postgresql16 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 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)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
