Multiple integer overflows in the DPRPC library (DPRPCNLM.NLM) NDPS/iPrint module in Novell Distributed Print Services in Novell NetWare 6.5 SP3 SP4 and SP5 allow remote attackers to execute arbitrary code via an XDR encoded array with a field that specifies a large number of elements which triggers the overflows in the ndps_xdr_array function.
