Same piece of code main-win.c doesn't look too trustworthy 
to me either:

    690     int error = jpegtran (filename, "/tmp/rot.jpg" , code);
    691     if(error)
    692         return error;
    693 
    694     //now copy /tmp/rot.jpg back to the original file
    695     char command[strlen(filename)+50]; //this should not generate buffer owerflow
    696     // MS: didn't know, how to make it better, maybe an own copy routine
    697     sprintf(command,"cp /tmp/rot.jpg \"%s\"",filename);
    698     system(command);

Anyone played with crafted file names?
Cheers
Nico
