  KillProcess "FileDescription" Local Buffer Overflow
------------------------------------------------------------------------


SUMMARY

"The  <http://orangelampsoftware.com/> KillProcess application can 
terminate almost any application on an PC running Microsoft Windows, 
including Windows Services and applications being debugged (but not while 
at a breakpoint) in a matter of a millisecond."

Lack of proper length checking allows attackers to cause the KillProcess 
to execute arbitrary code by overflowing one of its internal buffers.

DETAILS

Vulnerable Systems:
 * KillProcess version 2.20 and prior

A malicious .exe file with a long FileDescription in its version resource 
can generate a buffer overflow in KillProcess, which in turn can be used 
to cause it to execute arbitrary code.
