Descriptions

An issue was discovered in Open-iSCSI through 2.0.875. A local attacker can cause the iscsiuio server to abort or potentially execute code by sending messages with incorrect lengths, which (due to lack of checking) can lead to buffer overflows, and result in aborts (with overflow checking enabled) or code execution. The process_iscsid_broadcast function in iscsiuio/src/unix/iscsid_ipc.c does not validate the payload length before a write operation.

Se ha descubierto un problema en versiones hasta la 2.0.875 de Open-iSCSI. Un atacante local puede provocar que el servidor iscsiuio se interrumpa o, posiblemente, ejecute código mediante el envío de mensajes con longitudes incorrectas. Debido a la falta de verificación, esto puede dar lugar a desbordamientos de búfer que den como resultado interrupciones (con la verificación de desbordamiento activada) o ejecución de código. La función process_iscsid_broadcast en iscsiuio/src/unix/iscsid_ipc.c no valida la longitud de la carga útil antes de una operación de escritura.
