"The remote Debian 10 host has a package installed that is affected by a vulnerability as referenced in the dla-3246
advisory.

  - Hawk is an HTTP authentication scheme providing mechanisms for making authenticated HTTP requests with
    partial cryptographic verification of the request and response, covering the HTTP method, request URI,
    host, and optionally the request payload. Hawk used a regular expression to parse `Host` HTTP header
    (`Hawk.utils.parseHost()`), which was subject to regular expression DoS attack - meaning each added
    character in the attacker's input increases the computation time exponentially. `parseHost()` was patched
    in `9.0.1` to use built-in `URL` class to parse hostname instead. `Hawk.authenticate()` accepts `options`
    argument. If that contains `host` and `port`, those would be used instead of a call to
    `utils.parseHost()`. (CVE-2022-29167)

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