This script is Copyright (C) 2009-2014 Tenable Network Security, Inc.


Synopsis :

The remote SMB server can be abused to execute code remotely.

Description :

The remote Windows host contains a vulnerable SMBv2 implementation with
the following issues :

- A specially crafted SMBv2 packet can cause an
infinite loop in the Server service. A remote,
unauthenticated attacker can exploit this to cause
a denial of service. (CVE-2009-2526)

- Sending a specially crafted SMBv2 packet to the Server
service can result in code execution. A remote,
unauthenticated attacker can exploit this to take
complete control of the system. (CVE-2009-2532,
CVE-2009-3103)
