SHC binary having problems with jailed user

[ajmeese7]

Hey there, I am trying to use an shc binary for a chrooted user on my system and I am running into an issue that has had me stumped for several days.

Whenever I run the compiled binary as a non-jailed user, I have no problems at all and it does what it is supposed to do. But when I run the script as the jailed user, it just outputs gibberish to the terminal and doesn't run the code inside the script. I have chmod'd the binaries to make them executable and chown'd them so the jailed user definitely has the permission to execute the script and the commands contained within.

When I run the commands within the compiled shell script manually, the user can do so without issues. But once it is converted into a binary the problem arises. Below is a simplified example of what I am attempting to accomplish:

#!/bin/bash

PASSWORD="passaword_here"

if [ -z $1 ]; then
  # Requires a password to run.
  echo "Usage: ./zork3.sh [password]"
  echo "Or if converted to binary form: zork3 [password]"
  exit 1
elif [ "$1" = "$PASSWORD" ]; then
  # Runs Zork III if the password is correct.
  frotz ./COMPILED/zork3.z3
else
  # If the password is incorrect, tell the user.
  echo "That is not the correct password!"
  exit 1
fi

The script I run to generate the binaries from the shell scripts:

#!/bin/bash

ls -A | grep -E "zork.\.sh" | while read -r file; do
  echo "Compiling $file..."
  sudo shc -U -f "$file" -o "${file%.*}"
done

Any assistance in resolving this would be appreciated, thanks!

I have this problem too. I executed shc for my commands in /usr/bin/ in docker system. This work amazing, and this commands is executable before i start this docker with new changes again.

I solved this problem by using -r flag. But it nothing good
