A vulnerability has been identified in Microsoft Windows Vista, which could be exploited by remote attackers to cause a denial of service. This issue is caused by an error within the "srv.sys" driver when processing malformed "WRITE_ANDX" SMB packets, which could be exploited by remote unauthenticated attackers to crash an affected system by sending malformed packets to an interface allowing NULL Sessions (e.g. "\LSARPC" on Windows Vista).
