Echo: postgresql-15: security update to 15.19postgresql-17: security update to 17.11

high Tenable Self-Hosted Container Security Plugin ID 458225

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Untrusted data inclusion in pg_dump in PostgreSQL allows a malicious superuser of the origin server to
 inject arbitrary code for restore-time execution as the client operating system account running psql to
 restore the dump, via psql \restrict meta-command input expansion. The fix for CVE-2025-8714 introduced
 \restrict and \unrestrict to block this attack, but \unrestrict itself was sufficient for an attack.
 pg_dumpall is also affected. pg_restore is affected when used to generate a plain-format dump. Non-core
 use of \restrict would be affected, but we've not identified non-core use. Versions before PostgreSQL
 18.6, 17.11, 16.15, 15.19, and 14.24 are affected. (CVE-2026-18408)

Solution

Update the postgresql-15 library and its related packages to version 15.19 or later.
