The NICM.SYS kernel driver 3.1.11.0 in Novell Client 4.91 SP5 on Windows XP and Windows Server 2003; Novell Client 2 SP2 on Windows Vista and Windows Server 2008; and Novell Client 2 SP3 on Windows Server 2008 R2, Windows 7, Windows 8, and Windows Server 2012 allows local users to gain privileges via a crafted 0x143B6B IOCTL call.

Integer overflow in the NWFS.SYS kernel driver 4.91.5.8 in Novell Client 4.91 SP5 on Windows XP and Windows Server 2003 and the NCPL.SYS kernel driver in Novell Client 2 SP2 on Windows Vista and Windows Server 2008 and Novell Client 2 SP3 on Windows Server 2008 R2, Windows 7, Windows 8, and Windows Server 2012 might allow local users to gain privileges via a crafted 0x1439EB IOCTL call.

Unspecified vulnerability in NWFS.SYS in Novell Client for Windows 4.91 SP4 has unknown impact and attack vectors, possibly related to IOCTL requests that overwrite arbitrary memory.

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.

Novell Challenge Response Client (LCM) 2.7.5 and earlier, as used with Novell Client for Windows 4.91 SP4, allows users with physical access to a locked system to obtain contents of the clipboard by pasting the contents into the Challenge Question field.

NICM.SYS driver 3.0.0.4, as used in Novell NetWare Client 4.91 SP4, allows local users to execute arbitrary code by opening the \\.\nicm device and providing crafted kernel addresses via IOCTLs with the METHOD_NEITHER buffering mode.

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.
