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.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
