CVE-2014-4138

Microsoft Internet Explorer 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 corrupción de memoria de Internet Explorer,' una vulnerabilidad diferente a CVE-2014-4130 y CVE-2014-4132.

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. In addition, the user must allow the web page to access the clipboard when so prompted.
The vulnerability relates to how Internet Explorer converts bitmap-format graphics to PNG-format graphics. A web page can define an image using SVG, which, when copied and pasted back into the document, will overflow a heap-based buffer. An attacker can leverage this vulnerability to execute code under the context of the current process.
