Description

 A remote overflow exists in l2tpd. The l2tpd program fails to check the boundary in the write_packet() function in control.c, resulting in a buffer overflow. By establishing an L2TP tunnel and then sending a specially crafted packet, a remote attacker can overflow a buffer, resulting in a loss of integrity.
