DESCRIPTION:
Luigi Auriemma has discovered multiple vulnerabilities in BroadWin
WebAccess Client, which can be exploited by malicious people to
compromise a user's system.

1) A format string error in the "OcxSpool()" method (bwocxrun.ocx)
can be exploited to corrupt memory via a specially crafted string.

2) An error in the "WriteTextData()" method (bwocxrun.ocx) when
handling an open file descriptor can be exploited to corrupt memory
by passing an arbitrary integer value in the "fpt" parameter.

3) An error in the "CloseFile()" method (bwocxrun.ocx) when handling
an open file descriptor can be exploited to corrupt memory by passing
an arbitrary integer value in the "fpt" parameter.

Successful exploitation of these vulnerabilities may allow execution
of arbitrary code.

The vulnerabilities are confirmed in bwocxrun.ocx version 1.0.0.10
included in WebAccess Client version 7.0. Other versions may also be
affected.

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