	Disclosure	Vulnerability CVE-2006-1315

Yet another SMB memory leak. There are tons of these in SRVSVC. The key to 
finding them is to force large padding values (ie. holes between 
DataOffset/ParameterOffset and end of packet). A quick hack is to use the 
SMB ECHO command with a non-aligned byte size. I have yet to see anything 
actually *useful* get leaked. The leak data usually contains parts of 
packets that I sent it previously - my few attempts at testing a busy 
domain controller never leaked anything I found interesting. Maybe McAfee 
found a way to leak larger blocks?
