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
