DESCRIPTION:
Luigi Auriemma has discovered a vulnerability in NCSS 2007, which can
be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to an array-indexing error in the
VCF132.OCX module when processing certain data and can be exploited
to corrupt memory via a specially crafted Spreadsheet file (".s0").

Successful exploitation may allow execution of arbitrary code, but
requires tricking a user into opening a malicious file.

The vulnerability is confirmed in version 07.1.21. Other versions may
also be affected.

SOLUTION:
Do not open files from untrusted sources.
