Description
Heap-based buffer overflow in the iscsi_add_notunderstood_response function in drivers/target/iscsi/iscsi_target_parameters.c in the iSCSI target subsystem in the Linux kernel through 3.9.4 allows remote attackers to cause a denial of service (memory corruption and OOPS) or possibly execute arbitrary code via a long key that is not properly handled during construction of an error-response packet.
Statement
This issue does not affect the versions of the Linux kernel as shipped with Red Hat Enterprise Linux 5 and 6 as those versions do not provide support for in-kernel iSCSI target.
Future kernel updates in Red Hat Enterprise Linux MRG 2 may address this flaw.
