Echo: postgresql-15: security update to 15.18postgresql-17: security update to 17.10

high Tenable Cloud Security Plugin ID 462362

Description

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

- Stack buffer overflow in PostgreSQL module "refint" allows an unprivileged database user to execute
arbitrary code as the operating system user running the database. A distinct attack is possible if the
application declares a user-controlled column as a "refint" cascade primary key and facilitates user-
controlled updates to that column. In that case, a SQL injection allows a primary key update value
provider to execute arbitrary SQL as the database user performing the primary key update. Versions before
PostgreSQL 18.4, 17.10, 16.14, 15.18, and 14.23 are affected. (CVE-2026-6637)

Solution

Update the postgresql-15 library and its related packages to version 15.18 or later.
