The rule "NETBIOS DCERPC ISystemActivator path overflow attempt little endian unicode" triggers whenever we run the Win2K3 RESKIT "sonar" tool.


This tool is described as:

Sonar.exe is a command-line tool that allows administrators to monitor key statistics and status about members of a file replication service (FRS) replica set. Administrators can use Sonar to watch key statistics on a replica set in order to monitor traffic levels, backlogs, and free space.

Either sonar is attempting an overflow attempt (which I doubt - it's a diagnostic tool - not a vuln scanner), or its a FP.

I have packet captures - but they contain internal host details so I won't include them here. Someone from Sourcefire is welcome to ask for them (I might even say yes! ;-)
