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

  - Within HostnameError.Error(), when constructing an error string, there is no limit to the number of hosts
    that will be printed out. Furthermore, the error string is constructed by repeated string concatenation,
    leading to quadratic runtime. Therefore, a certificate provided by a malicious actor can result in
    excessive resource consumption. (CVE-2025-61729)

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