Multiple arbitrary code execution vulnerabilities have been identified in PostgreSQL, affecting various functions and plugins including tsvector, tsquery, logical decoding plugin, regexp, pltcl, plperl, fuzzystrmatch, cursor lifecycle, POSIX timezone abbreviation, and pg_dump transform lists. These vulnerabilities are addressed in a security update released by Red Hat for PostgreSQL 15 and related versions. The update is rated as important by Red Hat Product Security and fixes several critical issues that could allow attackers to execute arbitrary code.

This security update for PostgreSQL 18 addresses multiple vulnerabilities affecting various components such as psql, logical decoding, pgcrypto, regexp, and others. The issues include heap buffer overflows that can lead to arbitrary code execution, type confusion, integer wraparound causing undersize allocations, privilege enforcement failures, and SQL injection risks. The update fixes these vulnerabilities to improve the security and stability of PostgreSQL 18 and related versions.

A heap buffer overflow vulnerability exists in PostgreSQL's to_char function for timestamptz data types. This flaw allows an attacker who controls the timezone input to execute arbitrary code with the privileges of the database operating system user by providing a long POSIX timezone abbreviation. Multiple PostgreSQL versions prior to 14.24, 15.19, 16.15, 17.11, and 18.5 are affected. A patch is available to address this issue.

CVE-2026-14669 is a heap-based buffer overflow vulnerability in PostgreSQL's to_char function for timestamptz data type. It allows an attacker who can control the timezone input to execute arbitrary code with the privileges of the database operating system user by providing a long POSIX timezone abbreviation. This vulnerability affects multiple PostgreSQL major versions prior to specific patch releases.
