4. A set of modifications to binaries to be applied by a patching
program. IBM operating systems often receive updates to the operating
system in the form of absolute hexadecimal patches. If you have modified
your OS, you have to disassemble these back to the source. The patches
might later be corrected by other patches on top of them (patches were said
to “grow scar tissue”). The result was often a convoluted
patch space and headaches galore.
5. [Unix] the
patch(1)
program, written by Larry Wall, which automatically applies a patch (sense
3) to a set of source code.
There is a classicstory of a tiger team
penetrating a secure militarycomputer that illustrates the danger inherent
in binary patches (or, indeed, any patches that you can't — or don't
— inspect and examine before installing). They couldn't find any
trap doors or any way to penetrate security of IBM's
OS, so they made a sitevisit to an IBM office (remember, these were
officialmilitary types who were purportedly on official business), swiped
some IBM stationery, and created a fakepatch. The patch was actually the
trapdoor they needed. The patch was distributed at about the right time
for an IBM patch, had officialstationery and all accompanying
documentation, and was dutifully installed. The installationmanager very
shortly thereafter learned something about proper procedures.
