Retrospective Protection utilizing Binary Rewriting

Buffer overflow vulnerabilities present a common threat. To encounter this issue, operating system support and compile-time security hardening measures have been introduced. Unfortunately, these are not always part of the shipped object code. We present design and implementation of BinProtect, a binary rewriting tool, capable of retrospectively protecting binaries, which have not been sufficiently secured at compile-time. To achieve this, we do not need source code or any additional information.
