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

The vulnerability is caused due to a boundary error in the "Login()"
method of the Read & Write Excel ActiveX control (RWXls.RWXlsCtrl.2).
This can be exploited to cause a stack-based buffer overflow via an
overly long string passed in the "Password" parameter.

Successful exploitation may allow execution of arbitrary code.

The vulnerability is confirmed in version 5.3.9.15 (YRWXls.ocx
5.3.7.321). Other versions may also be affected.

SOLUTION:
Set the kill-bit for the ActiveX control.
