Microsoft Windows Vista iphlpapi.dll buffer overflow
| win-vista-iphlpapi-bo (46742) |  High Risk |
Description:
Microsoft Windows Vista is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the Microsoft Device IO Control wrapped by the iphlpapi.dll file. By sending a specially-crafted DestinationPrefix PrefixLength value to the CreateIpForwardEntry2() function using the MIB.IPFORWARD_ROW2 structure, a local attacker with Network Configuration Operators group privileges or Admin group privileges could overflow a buffer and execute arbitrary code on the system with SYSTEM privileges or cause the application to crash.
Platforms Affected:
- Microsoft, Windows Vista SP1
- phion AG, netfence entegra 1.2
Remedy:
