AI-suggested

Red Hat provides an update for the affected RPMs. Operational mitigations include avoiding tar-format pg_dump archives from untrusted sources, using the custom (-F c) or directory (-F d) formats instead, restoring backups with pg_restore rather than executing restore.sql scripts directly, and ensuring backup commands run under dedicated, unprivileged OS accounts. These mitigations do not require restarting database services but may require changes to automation or manual backup workflows.

Description

A security advisory from Red Hat addresses vulnerabilities in Red Hat Hardened Images RPMs, including a notable flaw in PostgreSQL's pg_dump utility when using tar-format archives. This flaw allows a compromised database server to inject untrusted data, potentially leading to arbitrary code execution with the privileges of the client running the restore command. The advisory recommends avoiding tar-format backups from untrusted sources and using safer formats or tools for restoration.
