The remote Debian 10 host has a package installed that is affected by multiple vulnerabilities as referenced in the dla-3565 advisory.

  - Loofah is a general library for manipulating and transforming HTML/XML documents and fragments, built on     top of Nokogiri. Loofah < 2.19.1 contains an inefficient regular expression that is susceptible to     excessive backtracking when attempting to sanitize certain SVG attributes. This may lead to a denial of     service through CPU resource consumption. This issue is patched in version 2.19.1. (CVE-2022-23514)

  - Loofah is a general library for manipulating and transforming HTML/XML documents and fragments, built on     top of Nokogiri. Loofah >= 2.1.0, < 2.19.1 is vulnerable to cross-site scripting via the image/svg+xml     media type in data URIs. This issue is patched in version 2.19.1. (CVE-2022-23515)

  - Loofah is a general library for manipulating and transforming HTML/XML documents and fragments, built on     top of Nokogiri. Loofah >= 2.2.0, < 2.19.1 uses recursion for sanitizing CDATA sections, making it     susceptible to stack exhaustion and raising a SystemStackError exception. This may lead to a denial of     service through CPU resource consumption. This issue is patched in version 2.19.1. Users who are unable to     upgrade may be able to mitigate this vulnerability by limiting the length of the strings that are     sanitized. (CVE-2022-23516)

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