Descriptions
TinyXML through 2.6.2 has an infinite loop in TiXmlParsingData::Stamp in tinyxmlparser.cpp via the TIXML_UTF_LEAD_0 case. It can be triggered by a crafted XML message and leads to a denial of service.
TinyXML versiones hasta 2.6.2, presenta un bucle infinito en la función TiXmlParsingData::Stamp en el archivo tinyxmlparser.cpp por medio del caso TIXML_UTF_LEAD_0. Puede ser activado por un mensaje XML diseñado y conlleva una denegación de servicio
Wang Zhong discovered that TinyXML incorrectly handled certain inputs. If a user or an automated system were tricked into opening a specially crafted input file, a remote attacker could possibly use this issue to cause a denial of service.
