Open-iscsi: open-iscsi: ipv6 neighbor discovery missing option length validation in iscsiuio allows arp table poisoning

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. Additionally, the ARP table is updated unconditionally with attacker-controlled addresses from the packet headers. An attacker on the same network segment can send a minimal Neighbor Advertisement to poison the ARP table and redirect network traffic.
