Descriptions
Microsoft Internet Explorer 9 through 11 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted web site, as demonstrated by Sebastian Apelt and Andreas Schmidt during a Pwn2Own competition at CanSecWest 2014. NOTE: the original disclosure referred to triggering a kernel bug with the Internet Explorer exploit payload, but this ID is not for a kernel vulnerability.
Microsoft Internet Explorer 9 hasta la versión 11 permite a atacantes remotos ejecutar código arbitrario o provocar una denegación de servicio (corrupción de memoria) a través de un sitio web manipulado, según lo demostrado por Sebastian Apelt y Andreas Schmidt durante una competición Pwn2Own en CanSecWest 2014. NOTA: la divulgación original se refería al desencadenamiento de un error del kernel explotado con la carga de Internet Explorer, pero este ID no es para una vulnerabilidad del kernel.
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 CDispNodeBase objects. 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.
