Sounds pretty innocent, right? Wrong! It turns out that running ldd on an executable can result in executing arbitrary code. This article details how such executable can be constructed and comes up with a social engineering scenario that may lead to system compromise. I researched this subject thoroughly and found that it's almost completely undocumented."
