The file msystem.c contains a version of system(3), popen(3), and pclose(3) that provide considerably more security than the standard C functions. They are named msystem, mpopen, and mpclose, respectively. While I don't guarantee them to be PERFECTLY secure, they do constrain the environment of the child quite tightly, tightly enough to close the obvious holes.
