Description

This module exploits a vulnerability in the handling of the FEATHEADER record
by Microsoft Excel. Revisions of Office XP and later prior to the release of the
MS09-067 bulletin are vulnerable.

When processing a FEATHEADER (Shared Feature) record, Microsoft used a data
structure from the file to calculate a pointer offset without doing proper
validation. Attacker supplied data is then used to calculate the location of an
object, and in turn a virtual function call. This results in arbitrary code
execution.

NOTE: On some versions of Office, the user will need to dismiss a warning dialog
prior to the payload executing.
