The `ldd` utility is more vulnerable than you think. It’s frequently used by programmers and system administrators to determine the dynamic library dependencies of executables. Sounds pretty innocent, right? Wrong! It turns out that running `ldd` on an executable can result in executing arbitrary code. I researched this subject thoroughly and found that it was almost completely undocumented. This article details how such executable can be constructed and comes up with a social engineering scenario that may lead to system compromise.
