Description:
A vulnerability has been reported in Citrix Presentation Server, which can be exploited by malicious people to compromise a vulnerable system.
The vulnerability is caused due to a boundary error in a print provider (ccprov.dll) when handling arguments passed to the "EnumPrintersW()" and "OpenPrinter()" functions. This can be exploited to e.g. cause a stack-based buffer overflow by passing an overly long string (more than 130 bytes) as the first argument to the "OpenPrinter()" function through a local API call or RPC request.
Successful exploitation allows execution of arbitrary code.
The vulnerability reportedly affects Citrix MetaFrame XP and Presentation Server version 4.0 and prior.
Solution:
Apply hotfix (see vendor advisory for details).
Provided and/or discovered by:
