CVE-2011-0978

Desbordamiento de búfer basado en pila en Microsoft Office Excel permite a atacantes remotos ejecutar código de su elección a través de vectores relacionados con un registro de propiedades de eje, y el incremento indebido de un índice de matriz.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Microsoft Office. 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 application's usage of a specific field used for incrementing an index used in an array. Due to the application failing to verify the usage of the index into the array, the application will copy the contents of the specified element into a statically sized buffer on the stack. This can lead to code execution under the context of the application.
