    value:
"The version of XnView installed on the remote Windows host is earlier
than 1.98.1.  As such, it reportedly uses unsafe methods for
determining how to load executables.  Specifically, there is an issue
with the file search path, which could result in the insecure loading
of executables when using the 'Open containing folder' function. 

An attacker may be able to exploit this to execute arbitrary code with
the privileges of the running application."
