VERY IMPORTANT PATCH

Pros
Cons
Summary
This fixes a problem when a malicious user can purposly crash the application and while it's crashed, he can send a virus such as Nimbda or Code Red. This will eventually allow him FULL ADMINISTRATIVE RIGHTS to your entire network domain. The main threat applies to Windows NT/2000, since there is not really any "file level security" on Windows 9x/XP Home Edition.
