Microsoft Internet Explorer 7 for Windows XP SP2 and SP3; 7 for Server 2003 SP2; 7 for Vista Gold, SP1, and SP2; and 7 for Server 2008 SP2 allows remote attackers to execute arbitrary code via frequent calls to the getElementsByTagName function combined with the creation of an object during reordering of elements, followed by an onreadystatechange event, which triggers an access of an object that (1) was not properly initialized or (2) is deleted, aka "HTML Object Memory Corruption Vulnerability." Microsoft Internet Explorer 7 para Windows XP SP2 y SP3; 7 para Server 2003 SP2; 7 para Vista Gold, SP1 y SP2; y 7 para Server 2008 SP2 permite a los atacantes remotos ejecutar código arbitrario por medio de llamadas frecuentes a la función getElementsByTagName combinada con la creación de un objeto durante el reordenamiento de elementos, seguida por un evento onReadyStateChange, que desencadena un acceso de un objeto que (1) no se inicializó apropiadamente o (2) se elimina, también se conoce como "HTML Object Memory Corruption Vulnerability". This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Microsoft Internet Explorer. User interaction is required to exploit this vulnerability in that the target must visit a malicious page. The specific flaw exists when repeated calls are made to getElementsByTagName() and the reordering of the elements in the document causes an object to be allocated. The use of the event "onreadystatechange" during this operation improperly frees the previously allocated resource. • http://osvdb.org/54950 http://www.securityfocus.com/archive/1/504216/100/0/threaded http://www.securityfocus.com/bid/35234 http://www.securitytracker.com/id?1022350 http://www.us-cert.gov/cas/techalerts/TA09-160A.html http://www.vupen.com/english/advisories/2009/1538 http://www.zerodayinitiative.com/advisories/ZDI-09-039 https://docs.microsoft.com/en-us/security-updates/securitybulletins/2009/ms09-019 https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval • CWE-399: Resource Management Errors •
