Heap-based buffer overflow in the IMA_SECURE_DecryptData1 function in ImaSystem.dll for Citrix MetaFrame XP 1.0 and 2.0, and Presentation Server 3.0 and 4.0, allows remote attackers to execute arbitrary code via requests to the Independent Management Architecture (IMA) service (ImaSrv.exe) with invalid size values that trigger the overflow during decryption. Desbordamiento del búfer basado en montón en la función IMA_SECURE_DecryptData1 en la ImaSystem.dll para el Citrix MetaFrame XP 1.0 y 2.0, y Presentation Server 3.0 y 4.0, permite a atacantes remotos ejecutar código de su elección mediante una petición en el Independent Management Architecture (IMA) al servicio (ImaSrv.exe) con tamaños de valores no válidos que disparen el desbordamiento durante la desencriptación. This vulnerability allows attackers to execute arbitrary code on vulnerable installations of Citrix MetaFrame Presentation Server. Authentication is not required to exploit this vulnerability. The specific flaw exists within the routine IMA_SECURE_DecryptData1() defined in ImaSystem.dll and is reachable through the Independant Management Architecture (IMA) service (ImaSrv.exe) that listens on TCP port 2512 or 2513. The encryption scheme used is reversible and relies on several 32-bit fields indicating the size of the packet and the offsets to the authentication strings. • http://secunia.com/advisories/22802 http://securitytracker.com/id?1017205 http://support.citrix.com/article/CTX111186 http://www.securityfocus.com/archive/1/451337/100/100/threaded http://www.securityfocus.com/bid/20986 http://www.vupen.com/english/advisories/2006/4429 http://www.zerodayinitiative.com/advisories/ZDI-06-038.html https://exchange.xforce.ibmcloud.com/vulnerabilities/30148 •
