Description

 Microsoft SQL Server and Desktop Engine contain a flaw that may allow a remote attacker to cause a denial of service. The issue is due to a flaw in the keep-alive function in the SQL Resolution Service. If a remote attacker sends a specially crafted packet with a spoofed source address, the server will fall into a recursive loop sending packets to itself. Such an attack would consume system resources as well as bandwidth resources.
