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. Desbordamiento de búfer en el servicio Independent Management Architecture (IMA) de Citrix Presentation Server (MetaFrame Presentation Server) 4.5 y versiones anteriores, Access Essentials 2.0 y versiones anteriores, y Desktop Server 1.0 permite a atacantes remotos ejecutar código de su elección mediante un valor de tamaño inválido en un paquete al puerto TCP 2512 ó 2513. This vulnerability allows attackers to execute arbitrary code on vulnerable installations of Citrix Presentation Server. Authentication is not required to exploit this vulnerability. The specific flaw resides in the Independent Management Architecture service, ImaSrv.exe, which listens by default on TCP port 2512 or 2513. The process trusts a user-suppled value as a parameter to a memory allocation. • http://secunia.com/advisories/28508 http://support.citrix.com/article/CTX114487 http://www.kb.cert.org/vuls/id/412228 http://www.securityfocus.com/archive/1/486585/100/0/threaded http://www.securityfocus.com/bid/27329 http://www.securitytracker.com/id?1019231 http://www.vupen.com/english/advisories/2008/0172 http://zerodayinitiative.com/advisories/ZDI-08-002.html • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
