Descriptions

Multiple use-after-free vulnerabilities in Microsoft Internet Explorer 6 through 11 allow remote attackers to execute arbitrary code via unspecified vectors, as demonstrated by Sebastian Apelt and Andreas Schmidt during a Pwn2Own competition at CanSecWest 2014.

Múltiples vulnerabilidades de uso después de liberación de memoria en Microsoft Internet Explorer 6 hasta la versión 11 permiten a atacantes remotos ejecutar un código arbitrario a través de vectores no especificados, tal como fue demostrado por Sebastian Apelt y Andreas Schmidt durante una competición Pwn2Own en CanSecWest 2014.

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 handling of CAttrValue objects. An uninitialized variable in one of the functions can cause memory corruption. This can lead to remote code execution under the context of the program.
