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.

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.

Untrusted data inclusion in PostgreSQL psql COPY may allow a server administrator to elicit execution of data lines as psql commands, via error injection. If the "COPY FROM STDIN" or "\copy FROM STDIN" command fails before the server indicates that it awaits input rows, psql processes the in-line data rows as psql commands. "COPY FROM" with a filename is unaffected. The server administrator has no inherent control over the data rows, so a complete attack requires the attacker to separately acquire control of both the server and the data rows. Alternatively, an attacker controlling data rows alone might complete an attack through a coincidental error that they don't control. Versions before PostgreSQL 18.6, 17.11, 16.15, 15.19, and 14.24 are affected.
