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

  - A flaw was found in 389-ds-base. A remote, authenticated attacker could exploit a vulnerability in the     Simple Authentication and Security Layer (SASL) UNBIND process. By sending a specially crafted request,     the attacker can cause a connection to stall, leading to resource exhaustion and a Denial of Service (DoS)     for the server. (CVE-2026-78701)

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