Summary

CVE-2021-21366

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.

CVE-2022-39353

Mark Gollnick discovered that xmldom parses XML that is not well-formed
because it contains multiple top level elements, and adds all root nodes to
the `childNodes` collection of the `Document`, without reporting or throwing
any error. This breaks the assumption that there is only a single root node
in the tree, and may open security holes such as CVE-2022-39299 in
downstream applications.

For Debian 10 buster, these problems have been fixed in version
0.1.27+ds-1+deb10u2.

We recommend that you upgrade your node-xmldom packages.
