Object-code Buffer Overrun Evaluator
OBOE

    (OBOE) A tool by R. Banfi,
   D. Bruschi, and E. Rosti for the automatic detection of
   buffer overflow vulnerabilities in object code.  OBOE
   can be applied to operating system components as well as
   ordinary application programs.  It was designed for the
   system administrator to identify vulnerable programs before
   they are exploited.  Being automatic, OBOE can be run as a
   background process for the analysis of all potentially
   insecure programs installed on a Unix system.  It runs on
   HP-UX, Linux, and Sun Solaris.
