Stack-based buffer overflow in Novell Client 4.91 SP4 and earlier allows local users to cause a denial of service (crash) and possibly execute arbitrary code via a long username in the "forgotten password" dialog.

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.

Stack-based buffer overflow in the EnumPrinters function in the Spooler service (nwspool.dll) in Novell Client 4.91 SP2, SP3, and SP4 for Windows allows remote attackers to execute arbitrary code via a crafted RPC request, aka Novell bug 353138, a different vulnerability than CVE-2006-5854. NOTE: this issue exists because of an incomplete fix for CVE-2007-6701.

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 METHOD_NEITHER 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.
