Description

This module exploits a vulnerability found in Excel of Microsoft Office 2007.
By supplying a malformed .xlb file, an attacker can control the content (source)
of a memcpy routine, and the number of bytes to copy, therefore causing a stack-
based buffer overflow. This results in arbitrary code execution under the context of
the user.
