live data
|
|
|
|
n. 1. Data that is written to be interpreted and takes over program flow
|
|
when triggered by some un-obvious operation, such as viewing it. One use of
|
|
such hacks is to break security. For example, some smart terminals have
|
|
commands that allow one to download strings to program keys; this can be
|
|
used to write live data that, when listed to the terminal, infects it with a
|
|
security-breaking virus that is triggered the next time a hapless user
|
|
strikes that key. For another, there are some well-known bugs in vi that
|
|
allow certain texts to send arbitrary commands back to the machine when they
|
|
are simply viewed. 2. In C code, data that includes pointers to function
|
|
hooks (executable code). 3. An object, such as a trampoline , that is
|
|
constructed on the fly by a program and intended to be executed as code.
