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

The vulnerability is caused due to a design error that allows program
code within the "Load" event of a user-defined control to be
automatically executed when a project containing a form that uses the
malicious control is opened. This can be exploited to execute
arbitrary program code.

Successful exploitation requires that the user is e.g. tricked into
opening a Solution file in a malicious Visual Studio project.

The vulnerability has been confirmed in Microsoft Visual C# 2005
Express Edition. Other versions may also be affected.

SOLUTION:
Do not open Visual Studio project files from untrusted sources.
