The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Covert timing channel in comparison of MD5-hashed password in PostgreSQL authentication allows an attacker     to recover user credentials sufficient to authenticate. This does not affect scram-sha-256 passwords, the     default in all supported releases. However, current databases may have MD5-hashed passwords originating in     upgrades from PostgreSQL 13 or earlier. Versions before PostgreSQL 18.4, 17.10, 16.14, 15.18, and 14.23     are affected. (CVE-2026-6478)

Note that Nessus relies on the presence of the package as reported by the vendor.
