Descriptions

Use-after-free vulnerability in Microsoft Internet Explorer 6 through 11 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via vectors related to the CMarkup::IsConnectedToPrimaryMarkup function, as exploited in the wild in April 2014. NOTE: this issue originally emphasized VGX.DLL, but Microsoft clarified that "VGX.DLL does not contain the vulnerable code leveraged in this exploit. Disabling VGX.DLL is an exploit-specific workaround that provides an immediate, effective workaround to help block known attacks."

Vulnerabilidad de uso después de liberación de memoria en Microsoft Internet Explorer 6 hasta la versión 11 permite a atacantes remotos ejecutar código arbitrario o provocar una denegación de servicio (corrupción de memoria) a través de vectores relacionados con la función CMarkup::IsConnectedToPrimaryMarkup, tal como fue explotado activamente en abril de 2014. NOTA: este problema se enfatizó originalmente en VGX.DLL, pero Microsoft aclaró que "VGX.DLL no contiene el código vulnerable aprovechado en esta explotación. La deshabilitación de VGX.DLL es una solución específica para la explotación que aporta una solución inmediata y efectiva para ayudar a bloquear ataques conocidos".

Microsoft Internet Explorer contains a memory corruption vulnerability that allows remote attackers to execute code in the context of the current user.
