"The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple
vulnerabilities as referenced in the 9d9e9439-959e-11ed-b464-b42e991fc52e advisory.

  - Those using Xstream to seralize XML data may be vulnerable to Denial of Service attacks (DOS). If the
    parser is running on user supplied input, an attacker may supply content that causes the parser to crash
    by stackoverflow. This effect may support a denial of service attack. (CVE-2022-40151)

  - XStream serializes Java objects to XML and back again. Versions prior to 1.4.20 may allow a remote
    attacker to terminate the application with a stack overflow error, resulting in a denial of service only
    via manipulation the processed input stream. The attack uses the hash code implementation for collections
    and maps to force recursive hash calculation causing a stack overflow. This issue is patched in version
    1.4.20 which handles the stack overflow and raises an InputManipulationException instead. A potential
    workaround for users who only use HashMap or HashSet and whose XML refers these only as default map or
    set, is to change the default implementation of java.util.Map and java.util per the code example in the
    referenced advisory. However, this implies that your application does not care about the implementation of
    the map and all elements are comparable. (CVE-2022-41966)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
