Descriptions

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.

Desbordamiento de búfer basado en la función iscsi_add_notunderstood_response en drivers/target/iscsi/iscsi_target_parameters.c en el subsistema de destino iSCSI en Linux kernel hasta v3.9.4 lo que permite a atacantes remotos provocar una denegación de servicio (corrupción de memoria y OOPS) o posiblemente ejecutar código arbitrario a través de una clave larga que no se maneja adecuadamente durante construcción de un paquete de respuesta de error.
