A flaw was found in open-iscsi. This vulnerability allows a remote attacker on the same local network segment to cause a Denial of Service (DoS) in the iscsiuio daemon. By sending a specially crafted Internet Control Message Protocol version 6 (ICMPv6) Router Advertisement with a zero-length option, the attacker can trigger an infinite loop. This leads to sustained CPU usage, rendering the daemon unresponsive and impacting system availability. A secondary risk of out-of-bounds reads exists with a short IPv6 payload, though no memory corruption or data exposure has been confirmed.

An Incorrect Authorization vulnerability in open-iscsi allows unprivilidged local users to use the isscsiuio control socket.

An Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in open-iscsi allows remote MITM attackers to create root-owned files outside the database and inject lines into the record.
