Multiple stack-based buffer overflows in the Spooler service (nwspool.dll) in Novell Client 4.91 SP2 through SP4 for Windows allow remote attackers to execute arbitrary code via certain long arguments to the (1) RpcAddPrinterDriver, (2) RpcGetPrinterDriverDirectory, and other unspecified RPC requests, aka Novell bug 300870, a different vulnerability than CVE-2006-5854.

Multiple integer overflows in the DPRPC library (DPRPCW32.DLL) in Novell Client 4.83 SP3, 4.90 SP2 and 4.91 SP2 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 ndpsxdrarray function. NOTE: this was originally reported to be a buffer overflow by Novell, but the original cause is an integer overflow.
