OVERVIEW:

       A vulnerability has been identified in Novell NetIdentity prior to
       version 1.2.4.


IMPACT:

       This vulnerability could potentially allow the execution of arbitrary
       code as a result of a flaw that "...exists within xtangent.exe during
       the handling of RPC messages over the XTIERRPCPIPE named pipe."
       Successful exploitation could allow "... remote attackers to 
       dereference an arbitrary pointer which can be leveraged to execute
       code under the context of the system user." [1]


MITIGATION:

       The vendor recommends upgrading to the latest version of Novell
       NetIdentity. [2]
