A flaw was found in Expat (libexpat). If XML_DTD is undefined at compile time, a recursive XML Entity Expansion condition can be triggered. This issue may lead to a condition where data is expanded exponentially, which will quickly consume system resources and cause a denial of service.
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
