Signature Detail

SMB: Microsoft Windows RPC UPnP Memory Allocation Denial of Service

This signature detects attempts to exploit a known flaw in the Microsoft Windows Plug and Play service. A successful attack can result in a denial-of-service condition.

Extended Description

Microsoft Windows Plug and Play service is prone to a denial of service condition. This issue is caused by a malformed request to the service that causes virtual memory consumption. On Windows XP, a remote attacker must authenticate over RPC to exploit this issue using the originally described attack vector. Update: A reliable source has indicated that this issue is anonymously exploitable via named pipes or other MSRPC calls on Microsoft Windows XP SP2. This issue may be exploited by differing attack vectors than originally described by Microsoft.
