This bug report was also filed in Ubuntu and can be found at http://launchpad.net/bugs/607297 The description, from segooon, follows: Hi, I've just discovered that tesseract-ocr is vulnerable to rewriting any user file: DEBUG_WIN::DEBUG_WIN( //constructor .... length += sprintf (command + length, "\"stty opost; tty >/tmp/debug%d; while [ -s /tmp/debug%d ]\ndo\nsleep 1\ndone\" &\n", pid, pid); Here attacker can create link to any file in the system that user may write to. The only he has to know - the pid of process. As it is (last PID + 1) by default, it is not difficult to guess.
