DESCRIPTION:
A vulnerability has been reported in Microsoft Visual Studio, which
can potentially be exploited by malicious people to compromise a
user's system.

The vulnerability is caused due to a boundary error in the Masked
Edit ActiveX control (Msmask32.ocx). This can be exploited to cause a
stack-based buffer overflow by tricking a user into e.g. visiting a
malicious website, which initializes the object with an overly long
"Mask" parameter.

Successful exploitation may allow execution of arbitrary code.

The vulnerability is reported in Msmask32.ocx version 6.0.81.69
included in Microsoft Visual Studio 6.0. Other versions may also be
affected.

SOLUTION:
The vulnerability is reportedly fixed in Msmask32.ocx version
6.0.84.18.

Set the kill-bit for the affected ActiveX control.

PROVIDED AND/OR DISCOVERED BY:
Reported as a 0-day.
