A new vulnerability was reported in cmd5checkpw, which may be exploited by local attackers to obtain elevated privileges. The problem is that cmd5checkpw is installed "setuid" and does not drop privileges before calling "execvp()", so the invoked program retains the cmd5checkpw euid, which may be exploited by local users that know at least one valid /etc/poppasswd user/password combination, to read the /etc/poppasswd file.
