Use-after-free vulnerability in 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 by repeatedly adding HTML document nodes and calling event handlers, which triggers an access of an object that (1) was not properly initialized or (2) is deleted, aka "HTML Objects Memory Corruption Vulnerability." Vulnerabilidad de Uso de la Memoria Previamente Liberada en 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 mediante la adición repetida de nodos de documentos HTML y el llamado a los Controladores de Eventos, lo que desencadena un acceso de un objeto que (1) no se inicializó apropiadamente o (2) se elimina, también se conoce como "HTML Objects 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 repeatedly calling event handlers after adding nodes of an HTML document. When a specially crafted webpage is repeatedly rendered, memory is improperly reused after it has been freed. • http://osvdb.org/54949 http://www.securityfocus.com/archive/1/504209/100/0/threaded 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-09-038 https://docs.microsoft.com/en-us/security-updates/securitybulletins/2009/ms09-019 https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A6294 • CWE-399: Resource Management Errors •

Microsoft Internet Explorer 8 for Windows XP SP2 and SP3; 8 for Server 2003 SP2; 8 for Vista Gold, SP1, and SP2; and 8 for Server 2008 SP2 does not properly handle objects in memory, which allows remote attackers to execute arbitrary code via "malformed row property references" that trigger an access of an object that (1) was not properly initialized or (2) is deleted, leading to memory corruption, aka "HTML Objects Memory Corruption Vulnerability" or "HTML Object Memory Corruption Vulnerability." Microsoft Internet Explorer 8 para Windows XP SP2 y SP3; 8 para Server 2003 SP2; 8 para Vista Gold, SP1 y SP2; y 8 para Server 2008 SP2 no maneja apropiadamente los objetos en la memoria, lo que permite a los atacantes remotos ejecutar código arbitrario por medio de "malformed row property references" que desencadenan un acceso de un objeto que (1) no se inicializó apropiadamente o (2) se elimina, lo que conlleva a corrupción de la memoria, también se conoce como "HTML Objects Memory Corruption Vulnerability" o "HTML Object Memory Corruption Vulnerability". This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Microsoft Internet Explorer 8. User interaction is required to exploit this vulnerability in that the target must visit a malicious page. The specific flaw exists during the rendering of an HTML page with malformed row property references, resulting in a dangling pointer which can be abused to execute arbitrary code. Internet Explorer 7 is not affected. • http://osvdb.org/54951 http://www.securityfocus.com/archive/1/504208/100/0/threaded 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-09-041 https://docs.microsoft.com/en-us/security-updates/securitybulletins/2009/ms09-019 https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A6244 • CWE-787: Out-of-bounds Write •
