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.
