Cross-site request forgery (CSRF) vulnerability in Citrix Presentation Server 4.0 and 4.5, MetaFrame Presentation Server 3.0, and Access Essentials 1.0 through 2.0 allows remote attackers to execute arbitrary published applications, and possibly other programs, as authenticated users via the InitialProgram key in an ICA connection. NOTE: some of these details are obtained from third party information.

Buffer overflow in the Independent Management Architecture (IMA) service in Citrix Presentation Server (MetaFrame Presentation Server) 4.5 and earlier, Access Essentials 2.0 and earlier, and Desktop Server 1.0 allows remote attackers to execute arbitrary code via an invalid size value in a packet to TCP port 2512 or 2513.
