Summary
A flaw was found in xmldom. Two independent quadratic paths in the XML DOM (Document Object Model) parser can lead to a denial of service (DoS).
A remote attacker could exploit this by providing specially crafted XML input, causing the parser to repeatedly rescan malformed tag names or reindex and rebuild strings during normalization. This excessive processing consumes system resources, making the application unresponsive.
