chore(deps): update dependency xmldom to v0.5.0 [security]

[renovate]

This PR contains the following updates:

Package	Change	Age	Confidence
xmldom	0.1.31 → 0.5.0

GitHub Vulnerability Alerts

CVE-2021-21366

Impact

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.

Patches

Update to 0.5.0 (once it is released)

Workarounds

Downstream applications can validate the input and reject the maliciously crafted documents.

Commits

Fixes

• Avoid misinterpretation of malicious XML input - GHSA-h6q6-9hqw-rwfv (CVE-2021-21366)

  • Improve error reporting; throw on duplicate attribute
    BREAKING CHANGE: It is currently not clear how to consistently deal with duplicate attributes, so it's also safer for our users to fail when detecting them.
    It's possible to configure the DOMParser.errorHandler before parsing, to handle those errors differently.

    To accomplish this and also be able to verify it in tests I needed to

    • create a new Error type ParseError and export it
    • Throw ParseError from errorHandler.fatalError and prevent those from being caught in XMLReader.
    • export DOMHandler constructor as __DOMHandler

  • Preserve quotes in DOCTYPE declaration
    Since the only purpose of parsing the DOCTYPE is to be able to restore it when serializing, we decided that it would be best to leave the parsed publicId and systemId as is, including any quotes.
    BREAKING CHANGE: If somebody relies on the actual unquoted values of those ids, they will need to take care of either single or double quotes and the right escaping.
    (Without this change this would not have been possible because the SAX parser already dropped the information about the quotes that have been used in the source.)
