Technical details
The DHCPv6 option parser in iscsiuio calls strlen() on raw network data without first ensuring a NUL terminator is present, resulting in a buffer over-read into heap memory. An attacker on the same network segment can craft a malicious DHCPv6 Advertise message to trigger the flaw, leading to daemon crash, heap memory corruption, or iSCSI initiator name corruption.
