nwgina.dll in Novell Client 4.91 SP3 for Windows 2000/XP/2003 does not delete user profiles during a Terminal Service or Citrix session, which allows remote authenticated users to invoke alternate user profiles.

Buffer overflow in the Novell Distributed Print Services (NDPS) Print Provider for Windows component (NDPPNT.DLL) in Novell Client 4.91 has unknown impact and remote attack vectors.

Format string vulnerability in Novell Modular Authentication Services (NMAS) in the Novell Client 4.91 SP2 and SP3 allows users with physical access to read stack and memory contents via format string specifiers in the Username field of the logon window.

srvloc.sys in Novell Client for Windows before 4.91 SP3 allows remote attackers to cause an unspecified denial of service via a crafted packet to port 427 that triggers an access of pageable or invalid addresses using a higher interrupt request level (IRQL) than necessary.

Multiple buffer overflows in the Spooler service (nwspool.dll) in Novell Netware Client 4.91 through 4.91 SP2 allow remote attackers to execute arbitrary code via a long argument to the (1) EnumPrinters and (2) OpenPrinter functions.

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 ndps_xdr_array function. NOTE: this was originally reported to be a buffer overflow by Novell, but the original cause is an integer overflow.
