Ramblr: Making Reassembly Great Again

Static binary rewriting has many important applications in reverse engineering, such as patching, code reuse, and instrumentation. Binary reassembling is an efficient solution for static binary rewriting. While there has been a proposed solution to the reassembly of binaries, an evaluation on a realworld binary dataset shows that it suffers from some problems that lead to breaking binaries. Those problems include incorrect symbolization of immediates, failure in identifying symbolizable constants, lack of pointer safety checks, and other issues. Failure in addressing those problems makes the existing approach unsuitable for real-world binaries, especially those compiled with optimizations enabled.
