This uncontrolled recursion vulnerability occurs in the xmlCatalogXMLResolveURI function when an XML catalog contains a delegate URI entry that references itself.

This ultimately results in a segmentation fault, causing a Denial of Service (DoS) by crashing affected applications."},{"lang":"es","value":"Se encontró una falla en libxml2, una biblioteca de análisis XML.
