buffer overrun
(foldoc)		buffer overflow
buffer overrun

What happens when you try to store more data in
a buffer than it can handle. This may be due to a mismatch
in the processing rates of the producing and consuming
processes (see overrun and firehose syndrome), or because
the buffer is simply too small to hold all the data that must
accumulate before a piece of it can be processed. For
example, in a text-processing tool that crunches a line at a
time, a short line buffer can result in lossage as input
from a long line overflows the buffer and overwrites data
beyond it. Good defensive programming would check for
overflow on each character and stop accepting data when the
buffer is full.

See also spam, overrun screw.

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.
