[...] 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?
