CVE-2006-5861

Description:
Two vulnerabilities have been reported in Citrix Presentation Server, which can be exploited by malicious people to cause a DoS (Denial of Service) or compromise a vulnerable system.
1) An error exists within the "IMA_SECURE_DecryptData1()" function in ImaSystem.dll when decrypting authentication data. This can be exploited to cause a heap-based buffer overflow by sending specially crafted data to the Independent Management Architecture (IMA) service (default port 2512/tcp or 2513/tcp).
Successful exploitation may allow execution of arbitrary code.
2) An input validation error in the handling of certain packet types in the Independent Management Architecture (IMA) service can be exploited to crash the service.
Solution:
Apply hotfix (see vendor advisory for details).
Provided and/or discovered by:
1) Eric Detoisien and an anonymous person.
