Buffer overflow in the ScStoragePathFromUrl function
in the WebDAV service in Internet Information Services (IIS) 6.0
in Microsoft Windows Server 2003 R2 allows remote attackers to
execute arbitrary code via a long header beginning with
"If: <http://" in a PROPFIND request, as exploited in the
wild in July or August 2016.
Original exploit by Zhiniang Peng and Chen Wu.
