I'll share my story. I used to work at a popular Linux website hosting control panel company. Back in the early 2000's "frontpage extensions" were a thing that people used to upload their websites. Unfortunately, frontpage extensions required files to exist in people Linux home directories, and people would often mess them up or delete them. People would need their frontpage extension files "reset" to fix the problem. Fortunately, Microsoft provided a Linux binary to reset a users frontpage extension files. Unfortunately, it required root access to run. Also unfortunately, I discovered that a user could set up symlinks in their home directory to trick the binary into overwriting files like /etc/passwd. We ended up actually releasing a code change that would overwrite getuid with LD_PRELOAD so that the Microsoft binary would think it was running as root, just to prevent it from being a security hazard.
