Good new here: the bug has been fixed in the upstream:
- https://github.com/libexpat/libexpat/commit/16f87daae5a16132e479e4f71862128c7a915c73
- https://github.com/libexpat/libexpat/commit/b47dbc9745932c160893d433220e462bd605f8cd

Thus, rolling out a new version of expat would be enough to fix this in Chromium.
