SCA: security update for xmldom (GHSA-h6q6-9hqw-rwfv)

medium Tenable Cloud Security Plugin ID 415535

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - xmldom is a pure JavaScript W3C standard-based (XML DOM Level 2 Core) DOMParser and XMLSerializer module.
 xmldom versions 0.4.0 and older do not correctly preserve system identifiers, FPIs or namespaces when
 repeatedly parsing and serializing maliciously crafted documents. This may lead to unexpected syntactic
 changes during XML processing in some downstream applications. This is fixed in version 0.5.0. As a
 workaround downstream applications can validate the input and reject the maliciously crafted documents.
