– Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
systems running vulnerable versions of Novell's Privileged User Manager.

The specific flaw exists within the unifid.exe service which binds on
port 29010 for a protocol providing RPC-like functionality encapsulated
over SSL. This protocol allows a client to make a method call into a
module. The 'spf' RPC call is implemented unsafely allowing remote
attackers to load arbitrary modules over the network resulting in code
execution under the context of the service.
