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.

Parsing arbitrary HTML can consume excessive CPU time, possibly leading to denial of service.
