low Tenable Self-Hosted Container Security Plugin ID 458828

Description

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

 - Integer underflow in PostgreSQL ECPG allows a database server administrator to achieve temporary denial of
 service against the ECPG client via sending a bytea value lacking the mandatory prefix. The client
 overwrites a huge memory region with bytes outside attacker knowledge or control. This typically yields a
 simple SIGSEGV, but rare cases might achieve client-specific integrity impact via the write. Versions
 before PostgreSQL 18.6, 17.11, 16.15, 15.19, and 14.24 are affected. (CVE-2026-16241)

Solution

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