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.
