Buffer overflow in the extract_openvpn_cr function in openvpn-cr.c in
openvpn-auth-ldap (aka the Three Rings Auth-LDAP plugin for OpenVPN) 2.0.4
allows attackers with a valid LDAP username and who can control the
challenge/response password field to pass a string with more than 14 colons
into this field and cause a buffer overflow.
