Description:
Some vulnerabilities have been reported in Microsoft Windows, which can be exploited by malicious, local users to gain escalated privileges and by malicious people to cause a DoS (Denial of Service).

1) A NULL pointer dereference error in the Server driver (srv.sys) when processing "SMB_COM_TRANSACTION" SMB messages can be exploited by sending a specially crafted SMB message with a string that is not properly NULL terminated.

Successful exploitation crashes the system.

2) An error exists within the way the Microsoft Server Service handles certain network messages. This can be exploited to execute arbitrary code by sending a specially crafted network message.

Successful exploitation may allow the execution of arbitrary code, but requires valid user credentials.
