Microsoft has released a patch that eliminates a security
vulnerability in Microsoft(r) IIS 4.0 and 5.0. The vulnerability
could potentially allow a visitor to a web site to take a wide range
of destructive actions against it, including running programs on it.

This vulnerability is eliminated by the patch that accompanied
Microsoft Security Bulletin MS00-057. Customers who have applied

need to take additional action. Microsoft strongly urges all
customers using IIS 4.0 and 5.0 who have not already done so to apply
the patch immediately.
