-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Microsoft Windows. User interaction is
required to exploit this vulnerability in that the target must visit a

the properties of a "Class Name" variable a lack of bounds checking can
result in a stack overflow. Successful exploitation can lead to remote
code execution under the credentials of the logged in user.
