Descriptions

Stack-based buffer overflow in the print provider library (cpprov.dll) in Citrix Presentation Server 4.0, MetaFrame Presentation Server 3.0, and MetaFrame XP 1.0 allows local users and remote attackers to execute arbitrary code via long arguments to the (1) EnumPrintersW and (2) OpenPrinter functions.

Un desbordamiento de búfer en la región stack de la memoria en la biblioteca print provider (cpprov.dll) en Citrix Presentation Server versión 4.0, MetaFrame Presentation Server versión 3.0 y MetaFrame XP versión 1.0 permite a los usuarios locales y a los atacantes remotos ejecutar código arbitrario por medio de argumentos largos a las funciones (1) EnumPrintersW y (2) OpenPrinter.

This vulnerability allows remote attackers to execute arbitrary code on systems with vulnerable installations of Citrix Presentation Server, Metaframe Presentation Server or MetaFrame XP. Authentication is not required to exploit this vulnerability.
The specific flaw exists in a print provider installed by the Presentation Server. The cpprov.dll library doesn't properly handle certain invalid calls to the EnumPrintersW() and OpenPrinter() functions. For example, passing a string of 130 or more characters in the first argument to the OpenPrinter() function results in a stack-based buffer overflow and can be leveraged to execute code in the context of the Spooler service, which runs as the privileged LocalSystem account.
