Assured Recompilation of Vintage Executables via Binary Lifting: Unfreezing Legacy Software from Obsolete Toolchain Dependence

A lot of everyday infrastructure is powered by legacy software that depends on obsolete toolchains. Such software is literally “stuck in time” and cannot benefit from innovations in modern compilers such as automated security mitigations applied during compilation. There are often other undesirable consequences, such as a need to use outdated hardware platforms. Unfortunately, modernizing such legacy software isn’t as simple as taking the ancient source code (if it exists) and re-running it through a modern compiler. In practice, hidden undocumented dependencies on specific compiler versions, build systems, and other parts of older toolchains often make it infeasible to recreate legacy…
