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. The Cockpit 389 Console's LDAP editor constructs an ldapsearch command by     embedding an LDAP entry's distinguished name (DN) into a shell command string without proper escaping. An     LDAP user with delegated privileges to create or rename directory entries could craft a malicious DN     containing shell metacharacters. When a Cockpit administrator subsequently views the entry in the 389     Console, the embedded shell command executes with root privileges on the directory server host.
    (CVE-2026-19843)

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