x86 to LLVM Bitcode Translation Framework: McSema

x86 to LLVM Bitcode Translation Framework McSema lifts x86 and amd64 binaries to LLVM bitcode modules. McSema support both Linux and Windows binaries, and most x86 and amd64 instructions, including integer, FPU, and SSE operations. McSema is separated into two conceptual parts: control flow...

CVE-2017-7892

Sandstorm Cap'n Proto before 0.5.3.1 allows remote crashes related to a compiler optimization. A remote attacker can trigger a segfault in a 32-bit libcapnp application because Cap'n Proto relies on pointer arithmetic calculations that overflow. An example compiler with optimization that elides a...
