    Summary:

    Details: usr/log.c in iscsid in open-iscsi (iscsi-initiator-utils) before 2.0-865 uses a semaphore with insecure permissions (world-writable/world-readable) for managing log messages using shared memory, which allows local users to cause a denial of service (hang) by grabbing the semaphore.
