Description:
Patrik Karlsson has reported two vulnerabilities in Citrix Program
Neighborhood Agent, which can be exploited by malicious people to compromise
a user's system.

1) A boundary error in the caching of information received from servers can
be exploited to cause a stack-based buffer overflow and execute arbitrary
code on a client system.

2) A design error allows arbitrary shortcuts to be created on a client
system with the privileges of the logged in user. This can be exploited to
eg. execute arbitrary programs when a user logs in the next time by placing
a shortcut in the Startup folder.

Successful exploitation requires that the client has been configured to
point to a malicious server.

The following clients are affected:
* Program Neighborhood Agent for Win32
* Citrix MetaFrame Presentation Server client for WinCE (versions including
Program Neighborhood Agent)

Solution:
The vulnerabilities have been addressed in the listed client versions below,
which are available at:
http://www.citrix.com/English/SS/downloads/downloads.asp?dID=2755

* Program Neighborhood Agent for Win32 versions 9.0 and later.
* Citrix MetaFrame Presentation Server client for WinCE versions 8.33 and
later.
