Description :A flaw was found in the iscsiuio component of open-iscsi. The IPv6 Neighbor Discovery handler accesses link-layer address options at a fixed offset without verifying the packet contains them.

An attacker on the same network segment can send a minimal Neighbor Advertisement to poison the ARP table and redirect network traffic.
Severity: 7.1 | HIGH
