Multiple stack-based buffer overflows in the Spooler service (nwspool.dll) in Novell Client 4.91 SP4 for Windows allow remote attackers to execute arbitrary code via long arguments to multiple unspecified RPC functions, aka Novell bug 287919, a different vulnerability than CVE-2007-2954.

NWFILTER.SYS in Novell Client 4.91 SP 1 through SP 4 for Windows 2000, XP, and Server 2003 makes the \.\nwfilter device available for arbitrary user-mode input via METHODNEITHER IOCTLs, which allows local users to gain privileges by passing a kernel address as an argument and overwriting kernel memory locations.

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.
