Descriptions

Microsoft Internet Explorer 6 through 11 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted web site, aka "Internet Explorer Memory Corruption Vulnerability," a different vulnerability than CVE-2014-4143.

Microsoft Internet Explorer 6 hasta 11 permite a atacantes remotos ejecutar código arbitrario o causar una denegación de servicio (corrupción de memoria) a través de un sitio web manipulado, también conocido como 'vulnerabilidad de la corrupción de memoria de Internet Explorer', una vulnerabilidad diferente a CVE-2014-4143.

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 vulnerability relates to the way Internet Explorer tracks the relationship between two CSS stylesheets when one is imported by the other. The imported stylesheet continues to refer to its parent stylesheet even after the parent stylesheet is no longer valid. An attacker can leverage this vulnerability to execute code under the context of the current process.
