Red Hat Update Infrastructure (RHUI) container images are based on the latest RHUI RPM packages and the ubi9 or ubi9-init base images. This release updates to the latest version.

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 regular expression processing, allowing an attacker who can craft specific queries to execute arbitrary code with the privileges of the database operating system user. This issue arises from unanticipated data growth when text is processed through pg_wchar encoding. 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 vulnerability.

Heap buffer overflow in PostgreSQL regexp allows the query author to execute arbitrary code as the operating system user running the database, via text that would not pass encoding validation. This shares heritage with CVE-2026-2006, but this case involved unanticipated data growth when round-tripped through pg_wchar. Versions before PostgreSQL 18.6, 17.11, 16.15, 15.19, and 14.24 are affected.
