Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

roxmltree through 0.21.1 performs quadratic-time attribute and namespace validation during XML parsing without limits on attribute count. Attackers can craft XML documents with tens of thousands of attributes on a single element to consume excessive CPU time and cause denial of service.
