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

  - HTML::FormHandler versions through 0.40068 for Perl allow attacker selected method dispatch and resource     exhaustion because _apply_actions and add_error use error message text built from request data as a     Locale::Maketext bracket notation template. add_error hands its first argument to the language handle as     the Locale::Maketext message key, and the default handle's lexicon sets `_AUTO`, so a string that is not a     lexicon entry is compiled as a bracket notation template instead of being looked up. In a bracket group     the first token names a method called on the language handle and the remaining tokens are its arguments.
    Three kinds of text the library did not author reach that position. _apply_actions installs a     `$SIG{__WARN__}` handler that stores the warning text in `$error_message`, and a captured warning survives     a successful action, so a field carrying a numeric transform turns `Argument [sprintf,%50000000d,0]     isn't numeric` into the template; a warning quotes the submitted value verbatim, so the group is well     formed and dispatches. `$error_message ||= $tobj->validate($new_value)` takes a type constraint's own     failure message, which renders the rejected value through a partial dumper in bracket and comma form     (Devel::PartialDump when Moose can load it, Type::Tiny's own dumper always), so a field with `apply => [     Str ]` given a parameter sent more than once, which arrives as an array, gets `Reference [a,b] did not     pass type constraint Str` as its template, from a request that carries no bracket character of its own.
    A coercion or transform exception reaches it the same way. Beyond those, a validator whose message     contains the field value puts that value in the template directly, and add_error replaces the message list     with the contents of an arrayref first argument (`@message = @{$message[0]} if ref $message[0] eq     'ARRAY'`), so a value arriving as an array fills the argument slots from the same request as well. A     malformed group such as `[0]` makes the compile croak, and HTML::FormHandler::I18N::maketext and add_error     each re-raise that as a die, so process() throws. A well formed group naming sprintf reaches CORE::sprintf     with an attacker chosen field width. Any caller that applies a type constraint or a transform to an     untrusted field, or whose validator passes an untrusted field value to add_error, can be made to throw an     unhandled exception out of process(), or to allocate an arbitrary amount of memory in one request, and an     application whose language handle subclass defines side effecting public methods makes those callable with     attacker chosen arguments. The dumped type constraint message is bounded to the exception, because both     dumpers quote non-numeric elements so the method slot is never an attacker chosen name. The built-in     messages pass fixed templates with the value in an argument slot, where it stays inert, and the built-in     field types attach explicit message callbacks, so neither is affected.

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