Vulnerability Details

This vulnerability allows remote attackers to execute arbitrary code on 
vulnerable installations of Novell Netware. A valid IPC$ connection must be 
established in order to exploit this vulnerability.

The specific flaw exists within xtagent.exe during the handling of RPC 
messages over the XTIERRPCPIPE named pipe. Insufficient sanity checking 
allows remote attackers to dereference an arbitrary pointer which can be 
leveraged to execute code under the context of the system user.
