Description
Stack-based buffer overflow in Microsoft Device IO Control in iphlpapi.dll in Microsoft Windows Vista Gold and SP1 allows local users in the Network Configuration Operator group to gain privileges or cause a denial of service (system crash) via a large invalid PrefixLength to the CreateIpForwardEntry2 method, as demonstrated by a "route add" command. NOTE: this issue might not cross privilege boundaries.
