REDHAT-BUG-968036
First published: Tue May 28 2013(Updated: )
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 iscsi_check_key(), the error response packet, generated by iscsi_add_notunderstood_response(), 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. Acknowledgements: Red Hat would like to thank Kees Cook for reporting this issue.
