REDHAT-BUG-968036: High severity red hat linux vulnerability
A flaw was found in the way Linux kernel's iSCSI target processed large keys. If a key was larger than 64 bytes, as checked by iscsicheckkey(), the error response packet, generated by iscsiaddnotunderstoodresponse(), would still attempt to copy the entire key into the packet, overflowing the structure on the heap.
A remote attacker could use this flaw to escalate their privileges on the system.
