Descriptions

Microsoft Internet Explorer 7 and 8 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."

Microsoft Internet Explorer 7 y 8 permite a atacantes remotos ejecutar código arbitrario o causar una denegación de servicio (corrupción de memoria) a través de un sitio web malicioso, también conocido como "Internet Explorer Memory Corruption Vulnerability".

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 Print command. A CMarkup Element can be freed and used afterwards within the SaveToTempFile function. An attacker can leverage this situation to execute code under the context of the user running the browser.
