Descriptions
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.
Múltiples desbordamientos de búfer en el servicio de Spooler(nwspool.dll) en Novell Netware Client 4.91 hasta 4.91 SP2 permite a atacantes remotos ejecutar código de su elección a través de un gran argumentos a las funciones (1) EnumPrinters y (2) OpenPrinter.
This vulnerability allows remote attackers to execute arbitrary code on systems with vulnerable installations of the Novell Netware Client. Authentication is not required to exploit this vulnerability.
The specific flaw exists in a print provider installed by the Netware Client. The nwspool.dll library does not properly handle long arguments to the Win32 EnumPrinters() and OpenPrinter() functions. Exceeding 458 bytes in the first argument to OpenPrinter() or 524 bytes in the second argument to EnumPrinters() results in an exploitable buffer overflow within the Spooler service.
This vulnerability can be exploited remotely via Remote Procedure Call (RPC) requests to the Spooler service. The Spooler exposes the "spoolss" named pipe, which allows an anonymous user to issue certain spooler commands. These include the OpenPrinter() and EnumPrinters() calls required to exploit this vulnerability.
