Descriptions

Microsoft Internet Explorer 6 through 11 allows remote attackers to bypass the ASLR protection mechanism via a crafted web site, aka "Internet Explorer ASLR Bypass Vulnerability."

Microsoft Internet Explorer 6 hasta 11 permite a atacantes remotos evadir el mecanismo de protección ASLR a través de un sitio web manipulado, también conocido como 'vulnerabilidad de la evasión de ASLR de Internet Explorer.'

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 CAutoRange::GetRangeTopLeft function. By manipulating a document's elements an attacker can force a type confusion error. An attacker can leverage this vulnerability to execute code under the context of the current process.
