Description
libexpat through 2.5.0 allows recursive XML Entity Expansion if XML_DTD is undefined at compile time.
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.
