DNS cache poisoning attacks and by malicious people to cause a DoS,
disclose potentially sensitive information, and potentially

1) An error withing the Econet protocol implementation can be
exploited to cause a stack overflow by sending specially crafted
network traffic.

2) An error within the "econet_sendmsg()" function in
net/econet/af_econet.c when handling remote addresses can be
exploited to cause a crash.

3) An error within the "ec_dev_ioctl()" function in
net/econet/af_econet.c incorrectly enforces access restriction, which
can be exploited to assign an Econet address to arbitrary interfaces.
