Descriptions
Use-after-free vulnerability in Microsoft Internet Explorer 6 through 11 allows remote attackers to execute arbitrary code via crafted JavaScript code that interacts improperly with a CollectGarbage function call on a CMarkup object allocated by the CMarkup::CreateInitialMarkup function.
Vulnerabilidad de uso después de liberación en Microsoft Internet Explorer 8 permite a atacantes remotos ejecutar código arbitrario a través de código JavaScript manipulado que no interactúa debidamente con una llamada de la función CollectGarbage function en un objeto CMarkup asignado por la función CMarkup::CreateInitialMarkup.
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 or open a malicious file.
The specific flaw exists within the handling of CMarkup objects. The allocation initially happens within CMarkup::CreateInitialMarkup. The free happens after the execution of certain JavaScript code followed by a CollectGarbage call. By manipulating a document's elements an attacker can force a dangling pointer to be reused after it has been freed. An attacker can leverage this vulnerability to execute code under the context of the current process.
