FreeBSD Security Advisory FreeBSD-SA-02:06 - The sudo port prior to sudo-1.6.4.1 contains a local root vulnerability. If a user who has not been authorized by the system administrator (listed in the 'sudoers' file) attempts to use sudo, sudo will send an email alert. When it does so, it invokes the system mailer with superuser privileges, and with most of the user's environment intact.
