Microsoft Internet Explorer 6, 7, and 8 does not properly handle objects in memory, which allows remote attackers to execute arbitrary code by accessing an object that (1) was not properly initialized or (2) is deleted, leading to memory corruption, aka "HTML Element Memory Corruption Vulnerability." Microsoft Internet Explorer 6, 7 y 8 no manejan correctamente los objetos en memoria, permitiendo a atacantes remotos ejecutar código arbitrario mediante el acceso a un objeto que (1) no se ha iniciado correctamente o (2) es eliminado, lo que genera una corrupción de memoria, también conocido como "vulnerabilidad de corrupción de memoria en un elemento HTML." 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 be convinced of visiting a malicious page or opening a malicious file. The specific flaw exists within usage of a particular element that's part of the Timed Interactive Multimedia Extensions component of the browser. By removing an element referenced by a tag used for implementing an animation, the application can be made to access an element that has been previously freed. • http://www.securitytracker.com/id?1024872 http://www.us-cert.gov/cas/techalerts/TA10-348A.html https://docs.microsoft.com/en-us/security-updates/securitybulletins/2010/ms10-090 https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A12322 • CWE-908: Use of Uninitialized Resource •
